Case Report: Individualization of Intensive Transactional Analysis Psychotherapy on the Basis of Ego Strength

In intensive transactional analysis psychotherapy (ITAP), intensity is obtained with both technical expedients and the relational manner with the patient. In ITAP, the therapist modulates pressure and support commensurately to the patients' ego strength. In the present article, we contrast two clinical cases of young adults in which ego strength produced different therapy outcomes and processes. We present excerpts of the psychotherapy process that illustrates technical aspects of ITAP as well as the therapist's attitude that we describe as holding. We show quantitative therapy outcomes consisting of effects size values of changes in Clinical Outcome in Routine Evaluation—Outcome Measure scores in baseline, treatment, and follow-up phases and qualitative outcome evaluated with the Change Interview at the end of the therapy. In the patient with high ego strength, we observed a rapid improvement and a complete recovery at the end of the therapy, whereas the results of the patient with low ego strength were less consistent (more fluctuations in Clinical Outcome in Routine Evaluation—Outcome Measure scores including deterioration but good qualitative outcome). We conclude that quantitative and qualitative outcome data, together with process observations, are required to have a complete picture of therapy effectiveness. Moreover, we conclude that qualitative ego strength is not a limitation for the use of expressive therapy such as ITAP, but rather, it is an important variable that should be considered to dose confrontations and support.


INTRODUCTION
Intending to increase intensity in therapeutic intervention, intensive transactional analysis psychotherapy (ITAP) is short-term psychodynamic psychotherapy that integrates transactional analysis (Berne, 1961;Schiff, 1975;Goulding and Goulding, 1979) with brief psychodynamic psychotherapy approaches (Malan, 1976;Davanloo, 1994;Fosha, 2000;Abbass, 2015). In ITAP, intensity is considered to be related to the therapist's activity, which is enhanced with both technical expedients and the relational manner with the patient.
At the technical level, the intrapsychic triangle and the interpersonal triangle are used by ITAP therapists for the optimization of interventions in a psychotherapy session. The intrapsychic triangle guides the therapist in analyzing intrapsychic dynamics among impulse, anxiety, and defense (Menninger, 1958;Malan, 1976;Davanloo, 1994). According to the psychoanalytic tradition, an impulse is a manifestation of the Id (Freud, 1923). In the ITAP model, it is broadly defined as any spontaneous manifestations of the functioning of the person, including a person's emotions, needs, creativity, and aspirations. Anxiety is a negative emotional activation that emerges in the presence of an obstacle to the satisfaction of impulses. Thus, anxiety is a signal of internal danger for the person (Freud, 1923). Educational and social restrictions are examples of obstacles to the satisfaction of impulses. Against impulse and related anxiety, the person may unconsciously use defenses (Frederickson et al., 2018;Grecucci et al., 2020a,b). Several defense mechanisms have been described in psychoanalysis, from forms of avoidance of disturbing thoughts or memories (e.g., denial or suppression) to severe distortions of reality (e.g., projections or delusions) (Vaillant, 1992). In ITAP, the therapist aims for impulse emersion. In pursuing this aim, he/she notes every anxiety manifestation as a signal of a covered impulse, and he/she confronts the patient with defenses that blocks the emersion of the impulse.
The intrapsychic triangle is used jointly with the interpersonal triangle, which guides the therapist in analyzing repetitive relational patterns in the person, exploring such patterns across different relational situations (Menninger, 1958). Here-andnow relational difficulties reported by the patients (current relationship) are explored, comparing them with relational experiences with the therapist in psychotherapy sessions (therapeutic relationship) and with past relationships in which repetitive relational patterns may have been formed as an effect of traumatic experiences. Thus, in the ITAP model, psychic functioning is described as interconnections of impulse, anxiety, and defenses, which have originated in past relationships and which can be enacted in here-and-now relationships (current relationships and/or therapeutic relationship) (Sambin, 2018a).
At the relational level, the therapist modulates the technique based on the level of the patient's anxiety manifestations, holding the patient during the exploration of intrapsychic and interpersonal triangles. The concept of holding refers to a relational attitude characterized by the full presence of the therapist in the relationship, with a moment-by-moment evaluation of the resources made available by the patient throughout the session (Scottà, 2018). On the basis of available resources, the therapist modulates pressure-a very active attitude, which intensifies psychotherapy sessions by moving the attention of the patient through the various vertexes of the ITAP triangles-and support (Sambin, 2018b). In other words, the therapist applies pressure and support commensurately according to the ego strength, a psychodynamic concept referring to a set of capacities including individual resilience, identity integration, personal resources, ability to maintain satisfactory interpersonal relationships, and self-esteem (Freud, 1923;Lake, 1985). Thus, ego strength may strongly influence the actual duration and intensity of ITAP, as well as the evolution of the psychotherapy process toward the psychotherapy outcome.
Psychotherapists have long realized that treatment should be tailored to the individuality of the patient. As part of the what works for whom approach (Roth and Fonagy, 2006;Norcross and Wampold, 2011), the identification of effective methods of adapting treatment to the individual patient (other than diagnosis) has become an object of investigation in psychotherapy research. Among individual factors, ego strength has been reported previously as being predictive of psychotherapy outcome (Barron, 1953;Conte et al., 1991;Laaksonen et al., 2013; but see also : Getter and Sundland, 1962). Also, variables attributable to ego strength, such as personality impairments in the patient (Hersoug et al., 2013), self-concept, and quality of object relations (Lindfors et al., 2014), have been associated with worse outcomes. With the present article, we contribute to this line of research by contrasting two clinical cases in which ego strength-the main element of calibration of intensity in ITAP-produced different therapy processes and outcomes. We consider that single-case methodology can be particularly suitable for the investigation of individual factors (Messina et al., , 2019. It allows longitudinal evaluations with a large number of observations to look in detail at how change unfolds over time during the therapy of each specific patient. Also, a single-case methodology is compatible with the use of qualitative measures that may be helpful in clarifying the influence of individual and contextual factors. In addition to quantitative and qualitative outcome measures, we also present excerpts of the psychotherapy process that illustrates (a) the impact of the use of ITAP triangles on impulse emersion and (b) therapist's attitude that we describe as holding. Evans et al., 2002). It is composed of 34 items that are scored on a 0-4 scale (from 0 = "Not at all" to 4 = "All or most of the time"). CORE-OM global scores allowed the classification of the patients on the basis of their distress level: healthy (score <0.6), low-level (score between 0.6 and 1.0), mild (score between 1.0 and 1.5), moderate (score between 1.5 and 2.0), moderately severe (score between 2.0 and 2.5), or severe (score >2.5). Moreover, four subscales allowed the evaluation of four outcome variables: well-being, psychological problems (depression, anxiety, somatic problems, and trauma), functioning (general functioning and functioning in close relationships and social relationships), and risk (risk to self and others). The Italian version of the CORE-OM shows good acceptability, internal consistency, and convergent validity (Palmieri et al., 2009).

Qualitative Assessment of Psychotherapy Outcome
Psychotherapy outcome was evaluated qualitatively through The Change Interview, a semi-structured interview that provides qualitative descriptions from patients of perceived change reported at the end of the therapy (Elliott et al., 2001). Patients are asked to identify the most relevant changes they made during the therapy and to evaluate them on a five-point scale: (a) if he/she expected the change (from 1 = expected change to 5 = surprising change); (b) how likely these changes would have been without therapy (from 1 = unlikely to 5 = likely without therapy), and (c) how important he/she feels these changes to be (from 1 = slightly important to 5 = extremely important).

Patients
Two young adult patients differing in ego strength as evaluated with the OPD-2 were selected from a larger clinical study testing ITAP efficacy. Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) diagnosis was provided for each patient, and they were asked about the goals of their therapy before starting the treatment. For both patients, this was the first experience of psychotherapy, and they were not treated pharmacologically.

Maria
Maria was a patient with a well-integrated structure according to the OPD-2 diagnosis. She was a 25-year-old female student. In her therapy, she focused mainly on her relational difficulties. She reported having difficulties in regulating her emotions with others. On the one hand, she suffered because sometimes she was aggressive with others, and then, she felt guilty as a consequence of this aggressiveness. On the other hand, she perceived not being free to express herself with her family, and she wanted to feel free to make her own decisions. She also suffered from anxiety and loss of concentration. In addition to these emotional difficulties, she wanted to cope with the loss of her dog (which was living with her ex-partner). With regard to the diagnosis, she saturated the DSM-5 criteria for dysthymic disorder and generalized anxiety disorder (American Psychiatric Association, 2013). Maria's CORE-OM scores at baseline were in the clinical range, except for the functioning score that was in the normal Frontiers in Psychology | www.frontiersin.org range (see Table 1 for scores). The total CORE-OM score was situated in the mild range of distress.

Fabio
Fabio was a patient with a low-integrated psychic structure, according to the OPD-2. He was a 24-year-old student. In his therapy, Fabio's main goal was to cope with severe anxious symptomatology that included social anxiety, claustrophobia, and panic attacks characterized by tunnel vision and temporary loss of reality perception. He reported having very low functioning in social relationships, with feelings of discomfort and freezing in social situations, conditions that fomented strong internal judgment and feelings of guilt that were the object of disturbing and continuous rumination. In the face of these difficulties, he wanted to become more spontaneous in social interactions. Fabio saturated the DSM-5 criteria for panic disorder in axis I and schizoid personality disorder in axis II. Although Fabio reported severe symptomatology and the therapists evaluated his personality as being low structured, Fabio's total scores compared with Italian normative data were within the nonclinical range at the beginning of the therapy (see Table 1).

Therapists
The same 32-year-old male therapist treated the patients. He is one of the founders of the ITAP approach, an expert in transactional analysis and brief dynamic therapy. He had a formal 4-year clinical training as a psychotherapist and had 3 years of experience in doing psychotherapy after training. The therapist discussed each clinical case in regular group supervision with the research team.

Research Team
In addition to the therapist, the research team was composed of three experienced researchers with both scientific (doctor of philosophy) and clinical training as psychotherapists and three advanced students. Two of the experienced researchers also had specific training as psychotherapy supervisors. The students participated in research team/clinical supervision groups, and they were also involved in data collection and analyses.

Recruitment and Ethical Issues
Patients were recruited from a waiting list of students who had psychological or relational difficulties and were voluntarily referred to therapy as part of a larger clinical study. The patients were voluntary students attending the same university as the research team, but they had no direct connection with the research team. The Ethical Committee of the University of Padua approved the research protocol. Before entering treatment, all patients received detailed descriptions of the research protocol, and they were informed that they were free to leave the research protocol at any moment without consequences for the continuation of their therapy. In the informed consent, a specific section for the use of video-recorded sessions was included, and it was specified that patients would not be identifiable on the basis of the material presented in scientific publications.

Data Collection
For the evaluation of psychotherapy outcome time series, longitudinal data were collected in three different phases: (a) Baseline included 5 weekly evaluations in 5 consecutive weeks before the beginning of the therapy (with the last evaluation immediately before the first session); (b) treatment included weekly evaluations realized immediately before each session (with the first evaluation immediately before the second session); (c) follow-up included evaluations realized at 1, 3, and 6 months after the end of the therapy. For each assessment, patients filled out the CORE-OM in the clinical psychology laboratory and in the presence of an external research assistant. During the first follow-up, a researcher carried out the Change Interview to collect qualitative data concerning patients' subjective perception of changes. Patients were informed that the therapist had no access to any research data provided.

Therapy
The treatment followed the procedures described in the ITAP manual . Sixteen sessions of ITAP therapy were planned as part of the research protocol. Maria had the planned number of sessions, whereas four additional sessions were provided to Fabio due to the clinical evolution throughout his therapy (see Results). The sessions were 50 min, with weekly frequency, with a total time of 4 months of treatment for Maria and 5 months for Fabio. The therapy was provided free of charge, and the patients were informed that they could withdraw from the study at any point, without any negative impact on their therapy.

Impulse Emersion
Here, we present two excerpts of the therapy of Maria and Fabio to illustrate how ITAP works. Each excerpt is introduced by a brief description of the context of what was occurring in the session and is followed by a brief conceptualization of the event in line with the ITAP model. The excerpts are verbatim transcripts with ellipses to show where words were deleted to shorten the presentation, and minimal encouragers (e.g., "Mmhmm") were dropped unless they had specific communication value. In brackets, we reported the position in the intrapsychic triangle (A = Anxiety, D = Defenses, or I = Impulse) and interpersonal triangle (P = Past, C = Current, or T = here-andnow in psychotherapy). Regarding the therapist's interventions, the positions to which the therapist moves are preceded by the symbol → (e.g., if the therapist explores or emphasizes an I/C, we use the symbol "→I/C"). In few cases, interventions escape from triangle classifications. Thus, we provided few additional categories. "Aw" refers to therapists' interventions aimed at stimulating aspects of awareness in the patients (→Aw) and the patient's responses indicating the acquisition of aspects of awareness (Aw); "E" refers to empathic interventions; "Al" refers to therapists' interventions aimed at the alliance. According to the consensual qualitative research method (Hill et al., 2005), research team members discussed to reach a consensus for the assignment of a category to each intervention.

Excerpt From Maria
This excerpt is taken from the eighth session. In this excerpt, the patient talks about an episode in her current life (C): she recently encountered a dog similar to the one she had to leave with her ex-boyfriend and became sad. The therapist aims to bring out the impulses activated in this episode by comparing the patient's defensive modes (D) in the here-and-now of therapy (T) to the emotions related to the loss of the dog (I). The patient is able to achieve a greater awareness regarding her tendency not to face conflict situations by giving in to the will of others (such as leaving her beloved dog to her ex-boyfriend). In the therapy extract, we can observe some elements that indicate a good level of ego strength in the case of Maria. First of all, it can be observed that anxiety is present at manageable levels and is mainly discharged at the level of the striated muscles (e.g., a lump in the throat). As typically happens with this type of manifestation of anxiety, the defenses are of an evolved type and concern the recognition of emotional aspects on a cognitive level with an avoidance of the actual emotion (the patient smiles while telling a sad episode so as not to come into contact completely with the sadness) or the repression ("I have really changed personality so I can't remember anything at all."). Finally, we see that Maria manages to understand the therapist's interventions without getting too anxious and easily acquires aspects of awareness.

Example From Fabio
This excerpt is taken from the third session. The patient starts with an episode from his own past (P) in which he recounts a situation where he had been very frightened, and his fear had not been accepted sufficiently. The patient easily links the terror he felt in P with the terror he currently feels during his anxiety crisis (C). The therapist encourages Fabio to focus on his emotions in recalling that episode in the here-and-now of the session (T), helping the patient to recognize some defensive tendencies and to get in touch with his own impulses of sadness (I).
F: I was on my way home and there was someone there, I met someone who was like, "Hey there, who are you?" Ah I got scared for a moment no, pretty scared for a child. . . Then this person I saw -then maybe I imagined -that he was following me from behind, so I had a moment and started running. In this second therapy extract, we can observe certain elements that are indicative of a low level of ego strength in Fabio's case. It can be noted that the anxious manifestations also involve cognitive-perceptive aspects (ringing in the ears), as well as those concerning the striated muscles (being stuck to the chair) (Abbass, 2015). To deal with these high levels of anxiety, the therapist uses many interventions of empathic validation and alliance verification, an attitude that highlights the holding attitude. Despite the low level of ego strength, the therapist, through his constant holding, allows Fabio to contact different aspects of impulse and to acquire some elements of awareness.

Quantitative Outcome
To quantify change, we calculated Hedge's g value for a corrected effect size (ES) of change in CORE-OM scores (global score, well-being, psychological problems, functioning, and risk) from baseline vs. treatment phases, baseline vs. follow-up phases, and treatment vs. follow-up phases (Rosenthal, 1994). The calculation of Hedge's g is based on the subtraction of the mean of one group from the other (M1-M2) and the division of the result by pooled the standard deviation. Both comparisons, "baseline vs. treatment" and "baseline vs. follow-up, " provided data concerning pre-vs. post-therapy; however, the former was influenced by fluctuations in the score during the therapy, whereas the latter was not. The additional "treatment vs. followup" comparison was useful in evaluating the maintenance of improvements obtained in the treatment phase.

High-Functioning Patient
Maria's CORE-OM scores at baseline were in the clinical range, except for the functioning score that was in the normal range (see Table 1 for scores). The total CORE-OM score was situated in the mild range of distress. As shown in Figure 1, a rapid improvement was observed in Maria's scores during the early sessions, with scores that decreased from the clinical to the nonclinical range for all CORE-OM subscales and with a global decrease from the mild range to the healthy range of distress. Thus, CORE-OM scores show a complete recovery for Maria. This description was confirmed in statistical analysis. In "baseline vs. treatment" comparisons, we found very large ES in CORE-OM total scores (ES = 3.76), as well as in subscales wellbeing (ES = 2.44) and psychological problems (ES = 2.99). A large ES was found for the functioning subscale (ES = 1.28), and a medium ES was also observed for the risk subscale (ES = 0.75).
Similarly, in "baseline vs. follow-up" comparisons, very large ESs were observed in CORE-OM total scores (ES = 2.88), in the well-being (ES = 4.03) and psychological problems subscales (ES = 1.01), and a large ES was observed in the functioning subscales (ES = 1.01). Only a small ES was found in the risk subscale (ES = 0.75) for the "baseline vs. follow-up" comparison.
The described improvements were maintained in follow-up evaluations, except for the risk subscale score that increased slightly in the last follow-up (6 months), influencing the global score of distress that moved from the healthy to the low-level range of distress in the follow-up phase (in the nonclinical range nonetheless). In line with this description, non-relevant changes were observed in the "treatment vs. follow-up" comparisons, indicating the maintenance of achieved CORE-OM scores.

Low-Functioning Patient
Although Fabio reported severe symptomatology and the therapists evaluated his personality as being low structured, Fabio's total scores compared with Italian normative data were within the nonclinical range at the beginning of the therapy. As shown in Figure 2, in this therapy, we can observe a progressive deterioration of the patient's CORE-OM score starting from the 11th session, with scores that increase from the non-clinical to  the clinical range for almost all CORE-OM subscales, and with a global increase from the low-level to the mild range of distress. A partial recovery of previous scores was achieved after the 18th session, but it remained in the mild range of distress.
The peculiar evolution of this case was also reflected in the statistical evaluations (see Table 1). In "baseline vs. treatment" comparisons, we found a medium effect size indicating the deterioration of the CORE-OM global score (ES = −0.68) and the psychological problems subscale (ES = −0.58). A large ES of deterioration was observed for the functioning subscale (ES = 1.01), whereas non-relevant changes were observed for the well-being and risk subscales.
In "baseline vs. follow-up" comparisons-which is less influenced by fluctuations in the score during the therapy-a large ES indicating improvement was observed for the well-being subscale (ES = 1.08). However, very large and large deteriorations in ES were observed, respectively, for the functioning (ES = −1.62) and risk subscales (ES = 1.23), whereas non-relevant changes were observed in the psychological problems subscale and in the CORE-OM global score.
The partial recovery achieved after the 18th session was maintained in follow-up evaluations. This recovery can be statistically observed in the "treatment vs. follow-up" comparisons where a medium ES was obtained for the CORE-OM global score (ES = 0.57), the well-being subscale (ES = 0.84), and the psychological problems subscale (ES = 0.54), whereas a medium ES of deterioration was maintained for the risk subscale (ES = −0.54), and non-relevant changes were observed for the functioning subscale.

Qualitative Outcome
Although quantitative data indicated a positive outcome for Maria and a negative outcome for Fabio, the qualitative evaluation of the psychotherapy outcome realized using the Change Interview method accounts for a very positive outcome for both patients. They reported several changes classified as very important and extremely important, and they considered many such changes as being unlikely without the therapy. Interestingly, most of the reported changes are in line with the declared aims of ITAP. They concern interpersonal relationships (analyzed with the interpersonal triangle), emotion regulation (analyzed with the intra-psychic triangle), and the improvement of selfrepresentations achieved through contact with self-relevant impulses. Detailed results of the Change Interview are reported in Tables 2, 3.

DISCUSSION
In the present study, we contrasted two clinical cases of patients with different levels of ego strength (or different levels of psychic structure integration) treated with ITAP, a new psychotherapy approach that aims toward the intensification of therapist intervention through the integration between transactional analysis and brief psychodynamic approaches. Following the what works for whom approach, our final aim was to reflect on the possibility that intensive interventions may be differently efficacious in helping patients with different levels of psychic structure integration.
If we consider ITAP outcomes evaluated using quantitative measure, CORE-OM data account for clearly different outcomes in the clinical cases analyzed in the present study. Mariathe patient with a well-integrated psychic structure-obtained a complete recovery, with a rapid improvement in early sessions and the maintenance of these results in follow-up evaluations. This pattern of change corresponds to a typical trajectory of change previously described in the literature (Duckworth et al., 2010;Vittengl et al., 2016). Moreover, these data are consistent with extremely and very important changes associated with the therapy as reported by Maria in qualitative evaluation, as obtained through the Change Interview. Thus, the efficacy of ITAP seems incontrovertible in the case of Maria.
Fabio, the patient with a low-integrated psychic structure, showed more fluctuations in CORE-OM scores during the therapy, and deterioration or non-relevant changes in outcome scores were observed in the "baseline vs. treatment" or "baseline vs. follow-up" comparisons. At first sight, these results support the hypothesis that ITAP may be more effective for patients with high ego strength compared with patients with more impaired psychic structure. This conclusion would be in line with previous studies showing that psychotherapy outcome is influenced by patients' ego strength (Barron, 1953;Conte et al., 1991;Laaksonen et al., 2013). However, an in-depth reflection is required to define a more realistic picture of Fabio's case. First, studies concerning the psychometric characteristics of CORE-OM have largely demonstrated that initial levels of distress are predictive of subsequent improvement after therapy (CORE Partnership, 2007). Namely, the chance of improvement is negligible for patients with CORE-OM global scores classified as healthy or low level (they cannot recover because they are already "healthy"), whereas it is more likely for patients in the clinical range. Despite the severe symptomatology reported by Fabio and the personality impairment observed by the therapist, the patient was situated in the non-clinical range in the initial assessment. Thus, statistically relevant changes were not expected for this patient. Second, qualitative data are not consistent with the hypothesis of a negative outcome. Indeed, Fabio reported several moderately to extremely important changes attributed to the therapy in the Change Interview. Furthermore, in the group supervision, the therapist reported important changes that defy standard evaluations. For example, we know that Fabio was overweight and lost weight during his therapy. Thus, an alternative hypothesis is that standard outcome measures are less suitable to capture therapeutic change in patients with psychic structure impairment.
Nevertheless, the deterioration observed in Fabio's CORE-OM scores requires reflection. Apparent deteriorations are expected in the early phases of some psychotherapy approaches. If the cognitive approach uses cognitive strategies to downregulate emotion, psychodynamic approaches-and more in general "expressive therapies"-are focused on affect recognition and expression (Greenberg and Pascual-Leone, 2006;Frederickson et al., 2018;Grecucci et al., 2018;Messina et al., 2020). As an example of expressive therapy, in ITAP sessions, the therapist is active in encouraging the patients' expression of their full experience of emotions and the associated impulses physically present in the body. This might be experienced as emotionally challenging by patients. Indeed, in previous studies, an initial trend to deterioration followed by a recovery toward positive outcomes has been noted as an effect of experiential and expressive techniques, such as imagery and chair work (van Asselt et al., 2008;Malogiannis et al., 2014). We consider that this temporary deterioration can be attributable to the progressive awareness of the patient's emotional difficulties in expressive therapies. For instance, it has been previously reported that some forms of deterioration in self-report questionnaires could reflect a less defensive attitude in the patients throughout therapy sessions (Mohr, 1995). In line with this interpretation, Fabio expressed the desire to continue his therapy after the end of this experience, suggesting an improved awareness concerning his psychological difficulties.
Finally, process examples reported in the present article may also help in reflecting the real efficacy of ITAP in the considered cases. As showed in the illustrative excerpts, despite the differences in available psychic resources in Maria's and Fabio's cases, both subjects were able to follow the therapist's analyses of intrapsychic and interpersonal triangles reaching the expression of their repressed impulses. The main difference between Maria and Fabio was that fewer  psychic resources in Fabio required longer therapy and more caution in confrontations during the intervention, with the adoption of a supportive approach. In this regard, we consider that the observation of verbatim interactions of the therapeutic dyad is an irreplaceable element for the judgment of therapy effectiveness.
The results of the present study should be considered in light of the limitation of single-case methodology. Although patients involved in the study are representative of patients seen in clinical practice, any generalization of our results must be avoided due to the small number of patients considered. At the same time, exactly due to the specificity of single-case methodology, this study extended previous knowledge regarding the influence of ego strength on psychotherapy outcome by documenting the efficacy of ITAP therapy for patients with different ego strengths. Thus, we conclude that ego strength is not a limitation for the use of expressive therapy such as ITAP, but rather it is an important variable that should be considered to dose confrontations and support during psychotherapy sessions, with more support (and probably longer therapy) for patients with less ego strength.
