<abstract>
<p><bold>Background:</bold> Committed action is one of the core processes of psychological flexibility derived from acceptance and commitment therapy. It has not been widely investigated in mainland China as appropriate measures are lacking. The current study aimed to validate a Chinese (Mandarin) version of the Committed Action Questionnaire (CAQ-8) in a non-clinical college sample and to explore whether committed action would have a mediating effect in the association between experiential avoidance (EA) and life satisfaction.</p>
<p><bold>Methods:</bold> We translated the CAQ-8 into Chinese (Mandarin). A total of 913 Chinese undergraduates completed a set of questionnaires measuring committed action, EA, mindful awareness, anxiety, depression, stress, and life satisfaction. For test&#x2013;retest reliability, 167 respondents completed the CAQ-8 again 4 weeks later.</p>
<p><bold>Results:</bold> The entire scale of CAQ-8 (Mandarin) and two subscales showed adequate internal consistency and acceptable test&#x2013;retest reliability. Confirmatory factor analyses confirmed the two-factor structure and the convergent and criterion validity were acceptable. Committed action was correlated with less EA, more mindful awareness, less depressive symptoms, less anxiety, less stress, and more life satisfaction. In bootstrap mediation analyses, committed action partially mediated the association between EA and life satisfaction.</p>
<p><bold>Conclusion:</bold> The results suggest that the CAQ-8 (Mandarin) is a brief, psychometrically sound instrument to investigate committed action in Chinese populations, and the relationship between EA and life satisfaction was partially explained by committed action. This study provides new information about the usefulness of CAQ-8 and supports the assumption that committed action may be considered a promising factors for improving life satisfaction who have involved in EA among an educated non-clinical population.</p>

<title>Introduction</title>
<p>As a third-wave cognitive behavioral therapy, acceptance and commitment therapy (ACT) has attracted much interest during the last two decades. For instance, a growing body of research has found that ACT, aiming at fostering psychological flexibility, is an effective treatment for psychological distress of university students (<xref ref-type="bibr" rid="B46">Muto et al., 2011</xref>; <xref ref-type="bibr" rid="B49">R&#x00E4;s&#x00E4;nen et al., 2016</xref>; <xref ref-type="bibr" rid="B30">Juncos et al., 2017</xref>; <xref ref-type="bibr" rid="B36">Levin et al., 2017</xref>, <xref ref-type="bibr" rid="B37">2020</xref>; <xref ref-type="bibr" rid="B22">Gr&#x00E9;goire et al., 2018</xref>; <xref ref-type="bibr" rid="B59">Viskovich and Pakenham, 2020</xref>). Psychological flexibility refers to the ability to completely get into contact with the present moment and either stick to or modify behaviors according to values and situational prospects (<xref ref-type="bibr" rid="B24">Hayes et al., 1999</xref>, <xref ref-type="bibr" rid="B25">2006</xref>). It includes six different but interconnected therapeutic subprocesses: acceptance, cognitive defusion, self-as-context, contact with the present moment, values, and committed action (<xref ref-type="bibr" rid="B24">Hayes et al., 1999</xref>, <xref ref-type="bibr" rid="B25">2006</xref>, <xref ref-type="bibr" rid="B26">2012</xref>). Many studies have shown that psychological flexibility may be a basic aspect of mental health and wellbeing, while psychological inflexibility is a risk factor for psychopathologies, such as chronic pain (<xref ref-type="bibr" rid="B38">Lin et al., 2018</xref>; <xref ref-type="bibr" rid="B17">Gentili et al., 2019</xref>), psychological distress, somatization, anxiety, or depression (<xref ref-type="bibr" rid="B32">Kashdan and Rottenberg, 2010</xref>; <xref ref-type="bibr" rid="B42">Masuda and Tully, 2012</xref>). Effective measurements to assess all six constructs are needed to obtain a better understanding of psychological flexibility and further insight into psychotherapeutic processes (<xref ref-type="bibr" rid="B14">Gagnon et al., 2017</xref>; <xref ref-type="bibr" rid="B54">Terhorst et al., 2020</xref>).</p>
<p>Several instruments have been developed to measure aspects of psychological flexibility, including cognitive defusion (<xref ref-type="bibr" rid="B18">Gillanders et al., 2014</xref>), acceptance (<xref ref-type="bibr" rid="B4">Bond et al., 2011</xref>), present-focused awareness (<xref ref-type="bibr" rid="B6">Brown and Ryan, 2003</xref>), self as context (<xref ref-type="bibr" rid="B62">Yu et al., 2016</xref>, <xref ref-type="bibr" rid="B63">2017</xref>; <xref ref-type="bibr" rid="B64">Zettle et al., 2018</xref>), and values (<xref ref-type="bibr" rid="B45">McCracken and Yang, 2006</xref>). Committed action is also a key component (<xref ref-type="bibr" rid="B16">Gal&#x00E1;n et al., 2019</xref>) but has been less studied (<xref ref-type="bibr" rid="B43">McCracken, 2013</xref>).</p>
<p>Committed action, focusing on effective and flexible actions following valued life directions (<xref ref-type="bibr" rid="B44">McCracken et al., 2015</xref>), is characterized by balanced patterns of behavior that can flexibly incorporate failure and discomfort as part of the process of attaining a goal (<xref ref-type="bibr" rid="B43">McCracken, 2013</xref>). Previous studies suggest that engaging in committed action is correlated with higher levels of pain acceptance, health and functioning (<xref ref-type="bibr" rid="B43">McCracken, 2013</xref>), quality of life (<xref ref-type="bibr" rid="B10">Coutinho et al., 2019</xref>), and mental health (<xref ref-type="bibr" rid="B1">&#x00C5;kerblom et al., 2016</xref>). It is also correlated with lower levels of psychosocial, physical, and independence-related disability (<xref ref-type="bibr" rid="B3">Bailey et al., 2016</xref>), pain intensity (<xref ref-type="bibr" rid="B43">McCracken, 2013</xref>), depression, anxiety, stress (<xref ref-type="bibr" rid="B14">Gagnon et al., 2017</xref>; <xref ref-type="bibr" rid="B56">Trindade et al., 2018</xref>), and procrastination (<xref ref-type="bibr" rid="B15">Gagnon et al., 2016</xref>).</p>
<p>There are two scales to measure committed action; the Engaged Living Scale (ELS) (<xref ref-type="bibr" rid="B57">Trompetter et al., 2013</xref>) and the Committed Action Questionnaire (CAQ) (<xref ref-type="bibr" rid="B43">McCracken, 2013</xref>), CAQ being more widely used. The original CAQ consists of 18 items, nine each of positively and negatively keyed items. A shortened version of the CAQ has been developed with eight items, which shows comparably satisfactory reliability and validity (<xref ref-type="bibr" rid="B44">McCracken et al., 2015</xref>). The CAQ-8 is psychometrically sound in various languages including Swedish (<xref ref-type="bibr" rid="B1">&#x00C5;kerblom et al., 2016</xref>), French (<xref ref-type="bibr" rid="B14">Gagnon et al., 2017</xref>), German (<xref ref-type="bibr" rid="B54">Terhorst et al., 2020</xref>), Portuguese (<xref ref-type="bibr" rid="B56">Trindade et al., 2018</xref>), and Chinese (Cantonese) (<xref ref-type="bibr" rid="B60">Wong et al., 2016</xref>). However, there is no Chinese (Mandarin) version of the CAQ-8, although it is the most common and official language of China. Mandarin has a different grammatical structure, vocabulary, character pattern, and writing system compared with Cantonese (<xref ref-type="bibr" rid="B53">Tardif et al., 2009</xref>; <xref ref-type="bibr" rid="B61">Yang and Wang, 2018</xref>). Thus, validation of a Chinese (Mandarin) version of the CAQ-8 is needed. One aim of the current study was to preliminarily validate the CAQ-8 (Mandarin) in a mainland non-clinical sample.</p>
<p>Experiential avoidance (EA), a pathological aspect of ACT, is a maladaptive psychological tendency that occurs when individuals are relatively unlikely to accept unwanted inner experiences (thoughts, memories, feelings, or emotions) (<xref ref-type="bibr" rid="B25">Hayes et al., 2006</xref>). People scoring more highly on EA tend to try to escape or control their private upsetting experiences, which restricts their meaningful behaviors and activities, including their committed actions (<xref ref-type="bibr" rid="B26">Hayes et al., 2012</xref>). Greater EA is related to reduced health benefits and life satisfaction (<xref ref-type="bibr" rid="B31">Kashdan et al., 2006</xref>; <xref ref-type="bibr" rid="B8">Chawla and Ostafin, 2007</xref>), suggesting that EA may be an important risk factor for life satisfaction (<xref ref-type="bibr" rid="B20">Graham et al., 2016</xref>; <xref ref-type="bibr" rid="B58">Valdivia-Salas et al., 2017</xref>; <xref ref-type="bibr" rid="B40">Lucas and Moore, 2020</xref>). For example, if someone feels anxious in social situations, then to avoid feeling anxious they may restrict social activities, decreasing life satisfaction. In a recent study of breast cancer patients and healthy individuals, the association between EA and depressive symptomatology was partially explained by committed action (<xref ref-type="bibr" rid="B56">Trindade et al., 2018</xref>). Another study of college students found that EA and committed action were significant mediators of the association between anxiety and psychological quality of life (<xref ref-type="bibr" rid="B10">Coutinho et al., 2019</xref>). Based on these findings, it was hypothesized that EA, committed action, and life satisfaction are interrelated. A second aim of the study was to examine whether committed action mediates the correlation between EA and life satisfaction. Additionally, we hypothesized that higher EA scores would be associated with lower committed action which, in turn, would be associated with lower life satisfaction.</p>

<sec id="S3.SS1">
<title>Participants</title>
<p>With the permission and assistance of teachers, 1,050 undergraduate students from the Hunan University of Chinese Medicine were asked to participate, providing an initial convenience sample of 930 undergraduate students who agreed to participate and gave written informed consent after being told the purpose and content of the study. All participants completed a paper version of the questionnaire which takes 30&#x2013;40 min, without any reward or course credit. Ultimately, 913 participants (268 men and 645 women), aged 16&#x2013;25 years (<italic>M</italic><sub><italic>age</italic></sub> = 18.84, SD = 1.25) provided fully completed questionnaires with no missing data, which gave a response rate of 98.2%. For test&#x2013;retest validity, 180 participants were conveniently selected a second time 4 weeks later in class, when they completed the CAQ-8 (Mandarin) again. Of them, 13 participants had not been tested the first time or did not answer all the questions, so they were deleted from the analysis. The valid sample used in the test&#x2013;retest analysis comprised 167 respondents. This study was approved by the Institutional Review Board of the Third Xiangya Hospital of Central South University (2020-S385).</p>

<title>Instruments</title>
<sec id="S3.SS2.SSS1">
<title>The Mandarin Chinese Version of the Committed Action Questionnaire-8</title>
<p>The primary CAQ-8 includes eight items with two subscales (<xref ref-type="bibr" rid="B32">Kashdan and Rottenberg, 2010</xref>), one positive subscale named values persistence (VP) and one negative subscale named non-reactive behavior (NB), with four items each. Participants are asked to rate each item on a seven-point Likert scale ranging from 0 (never true) to 6 (always true). Primary research found that the total scale, VP subscale, and NB subscale of CAQ-8 have good (respectively, &#x03B1; = 0.87, 0.87, and 0.80) reliability (<xref ref-type="bibr" rid="B44">McCracken et al., 2015</xref>).</p>
<p>We followed the recommended guidelines (<xref ref-type="bibr" rid="B5">Brislin, 1970</xref>) to translate the CAQ-8 from the original English version to Mandarin Chinese. First, after gaining permission for translation from the original author, Lance M. McCracken, forward translation (English to Mandarin Chinese) was conducted by a panel of bilingual psychological researchers. Next, two psychology professors, familiar with ACT, checked and revised the translation to make it suitable for the mainland Chinese population. Then, an independent professional bilingual translator performed a back-translation. After that, the original author of the CAQ-8 then examined and reviewed the back-translated questionnaire to ensure these two versions were identical in meaning. The final translated items were piloted on 10 undergraduate students with all participants reporting no misunderstanding.</p>
</sec>
<sec id="S3.SS2.SSS2">
<title>Acceptance and Action Questionnaire II</title>
<p>The seven-item Acceptance and Action Questionnaire II (AAQ-II) was used to measure EA (<xref ref-type="bibr" rid="B4">Bond et al., 2011</xref>). The response scale has a range of 1 (never true) to 7 (always true), a higher score indicated a higher degree of EA. From the initial validation study (&#x03B1; = 0.88) and another in college students in mainland China (&#x03B1; = 0.84), a good internal consistency was observed (<xref ref-type="bibr" rid="B7">Cao et al., 2013</xref>). In the current sample, AAQ-II also demonstrated good internal consistency (Cronbach&#x2019;s &#x03B1; = 0.87).</p>
</sec>
<sec id="S3.SS2.SSS3">
<title>Mindful Attention Awareness Scale</title>
<p>Present-moment awareness can be considered a fundamental component of mindfulness and it is most commonly measured with the 15-item Mindful Attention Awareness Scale (MAAS) (<xref ref-type="bibr" rid="B6">Brown and Ryan, 2003</xref>). It uses a seven-point scale from 1 (almost always) to 6 (almost never). Good internal reliability (&#x03B1; = 0.89; <xref ref-type="bibr" rid="B41">MacKillop and Anderson, 2007</xref>) was shown in the original validation study, and in a Chinese student sample (&#x03B1; = 0.85; <xref ref-type="bibr" rid="B11">Deng et al., 2011</xref>). In the current sample, MAAS also demonstrated good internal consistency (&#x03B1; = 0.87).</p>
</sec>
<sec id="S3.SS2.SSS4">
<title>Depression Anxiety and Stress Scale-21</title>
<p>Mental distress was measured by Depression Anxiety and Stress Scale-21 (DASS-21), which includes 21 items with three subscales reflecting three types of negative states: anxiety, depression, and stress (<xref ref-type="bibr" rid="B39">Lovibond and Lovibond, 1995</xref>). A four-point Likert scale was used to assess items, running from 0 (did not apply to me at all) to 3 (applied to me very much, or most of the time). Good internal reliabilities for the anxiety, depression, and stress subscales (&#x03B1; = 0.87&#x2013;0.94) were shown in the original version (<xref ref-type="bibr" rid="B2">Antony et al., 1998</xref>) and the Chinese version (&#x03B1; = 0.76&#x2013;0.79) (<xref ref-type="bibr" rid="B19">Gong et al., 2010</xref>). The reliability coefficients were 0.83 (depression), 0.78 (anxiety), and 0.81 (stress) in the current study.</p>
</sec>
<sec id="S3.SS2.SSS5">
<title>Multidimensional Students&#x2019; Life Satisfaction Scale</title>
<p>Life satisfaction of students was evaluated with the 40-item Multidimensional Students&#x2019; Life Satisfaction Scale (MSLSS) across five domains of family, friends, school, surroundings, and self (<xref ref-type="bibr" rid="B29">Huebner et al., 1998</xref>). Questions were rated using a single six-point Likert-type scale from 1 (disagree completely) to 6 (agree completely). Overall MSLSS score and five domain scores were calculated. Good internal reliability for the total scale (&#x03B1; = 0.91) was shown in the original validation study, and in a Chinese student sample (&#x03B1; = 0.90) (<xref ref-type="bibr" rid="B55">Tian and Liu, 2005</xref>). The reliability coefficient for the total scale was 0.92 in this study.</p>
</sec>

<sec id="S3.SS3">
<title>Statistical Analysis</title>
<p>Statistical analysis consisted of three parts. First, preliminary data analyses using descriptive statistics were conducted. Second, to ensure that the psychometric properties of the Mandarin Chinese version of the CAQ-8 were adequate, reliability, and validity analyses were conducted using IBM SPSS Statistics 24.0. Homogeneity was evaluated using corrected item-total correlations. To determine reliability, Cronbach&#x2019;s alpha was used for internal consistency, and test&#x2013;retest reliability used intraclass correlation coefficients (ICCs) based on a model of two-way random effects (<xref ref-type="bibr" rid="B34">Koo and Li, 2016</xref>).</p>
<p>Based on theory and previous research on the CAQ-8 (<xref ref-type="bibr" rid="B43">McCracken, 2013</xref>; <xref ref-type="bibr" rid="B57">Trompetter et al., 2013</xref>; <xref ref-type="bibr" rid="B44">McCracken et al., 2015</xref>; <xref ref-type="bibr" rid="B15">Gagnon et al., 2016</xref>; <xref ref-type="bibr" rid="B60">Wong et al., 2016</xref>; <xref ref-type="bibr" rid="B56">Trindade et al., 2018</xref>), two competing models were derived: a correlated two-factor model (two-factor model) and a general factor plus two subsidiary factors model (bifactor model). In the correlated two-factor model, every item was assigned to load on one of two factors, anticipated to represent the two subscales, with the two factors allowed to be correlated. The general factor plus two subsidiary factors model (bifactor model) hypothesized that CAQ-8 could be explained by three potential factors, namely, a general factor standing for the committed action and two factors representing the subscales. These three factors would not correlate with each other. We conducted confirmatory factor analysis (CFA) to examine which model best fitted the Chinese population. Maximum likelihood estimation was employed for CFA, using Mplus 8.0, to examine the factor structure. Since chi-square is sensitive to sample size, four commonly used indices were observed to test model fit. The Tucker&#x2013;Lewis index (TLI) and comparative fit index (CFI) should be above a recommended level of 0.90 to indicate good fit, while the standardized root-mean-square residual (SRMR) and the root-mean-square error of approximation (RMSEA) are acceptable when inferior to 0.08 (<xref ref-type="bibr" rid="B28">Hu and Bentler, 1999</xref>).</p>
<p>Convergent validity was investigated through the relationship between the CAQ-8 (Mandarin) and remaining theoretically linked measures, such as EA (AAQ-II) and present-moment awareness (MAAS), which are measures of psychological flexibility that originated from ACT and should conceptually be related. In addition, previous studies have found committed action to be a predictor of both mental distress (<xref ref-type="bibr" rid="B14">Gagnon et al., 2017</xref>; <xref ref-type="bibr" rid="B56">Trindade et al., 2018</xref>) and life satisfaction (<xref ref-type="bibr" rid="B10">Coutinho et al., 2019</xref>). Therefore, DASS-21 and MSLSS were used as measures of the criterion validity, expecting that CAQ-8 would be negatively correlated with mental distress, and positively correlated with life satisfaction. Additionally, hierarchical regression analyses were performed to assess the incremental validity of the CAQ-8 above that of the AAQ-II and MAAS as measures of related ACT processes, with depression, anxiety, stress, and MSLSS as dependent variables. In the first step, the AAQ-II and MAAS total scores were entered to predict the dependent variables. In the second step, the CAQ-8 total score was added. The incremental validity was evaluated by the change in variance from the second step.</p>
<p>The third part of the statistical analysis is the test of mediating effect. SPSS PROCESS was used to perform the path analyses (<xref ref-type="bibr" rid="B23">Hayes, 2013</xref>) to verify mediating effects. We tested Model 4, Hayes&#x2019; SPSS PROCESS model (<xref ref-type="bibr" rid="B23">Hayes, 2013</xref>), in which EA (AAQ-II) is the predictor, life satisfaction (MSLSS) the dependent variable, and committed action (CAQ) the mediator. We used bootstrapping with 5,000 samples to calculate the 95% CIs and the bias-corrected method of the indirect effects in all statistical analyses (<xref ref-type="bibr" rid="B23">Hayes, 2013</xref>). Based on the bootstrapping methods, the mediating effect was considered significant if the 95% the bias corrected confidence interval (BCCI) did not overlap with 0 (<xref ref-type="bibr" rid="B23">Hayes, 2013</xref>).</p>

<p>For CAQ-8, the mean scores were 29.90 &#x00B1; 7.04 (total scale), 15.10 &#x00B1; 4.39 (VP subscale), and 9.20 &#x00B1; 4.62 (NB subscale). The skewness of CAQ-8 items varied between &#x2013;0.66 and &#x2013;0.05 and kurtosis varied between &#x2013;0.58 and 0.10, all within the recommended range with absolute values not above 3 and 10, respectively (<xref ref-type="bibr" rid="B33">Kline, 2005</xref>). These findings suggest that the distributions of all items were relatively normal. Four weeks later, 167 participants fully completed the CAQ-8 a second time to evaluate test&#x2013;retest reliability, the mean score was 31.01 &#x00B1; 5.71.</p>

<title>Reliability</title>
<p>The homogeneity of the CAQ-8 was evaluated by examining corrected item-total correlations, and the results indicated that all of the item-total correlations were greater than the threshold of 0.30 (<xref ref-type="bibr" rid="B47">Nunnally and Bernstein, 1994</xref>) and had a range from 0.48 to 0.67. The Cronbach&#x2019;s alpha coefficients for the overall scale, NB subscale, and VP subscale were 0.77, 0.75, and 0.84, respectively, suggesting moderately high internal consistency, which surpassed acceptable &#x03B1; levels of between 0.60 and 0.70 (<xref ref-type="bibr" rid="B12">DeVellis, 1991</xref>). The ICC was used according to <xref ref-type="bibr" rid="B51">Shrout and Fleiss (1979)</xref> as an estimation of the test&#x2013;retest reliability index. By Shrout&#x2019;s (<xref ref-type="bibr" rid="B50">Shrout, 1998</xref>) criteria, below 0.40 was considered poor, 0.41&#x2013;0.60 ordinary, 0.61&#x2013;0.80 moderate, and above 0.80 good. The test&#x2013;retest reliability coefficients (<italic>n</italic> = 167) had ICC values of 0.79 for CAQ-8 total, 0.68 for VP subscales, and 0.68 for the NB subscales. These findings suggest moderate test&#x2013;retest reliability for the CAQ-8.</p>

<p>Two competing models, a two-factor model and a bifactor model, were tested. <xref ref-type="table" rid="T2">Table 2</xref> shows that only the two-factor model achieved an acceptable fit based on CFI, TLI, RMSEA, and SRMR for the present sample. The structure validity was supported by the two-factor model, which indicated that the items of CAQ-8 comprise two correlated factors. <xref ref-type="table" rid="T3">Table 3</xref> reports the results of factor loadings, which exceeded the 0.4 cut-off value ranging from acceptable to good (<xref ref-type="bibr" rid="B52">Tabachnick and Fidell, 2007</xref>).

<title>Mediation Analysis</title>
<p>As shown in <xref ref-type="table" rid="T4">Table 4</xref>, EA was correlated with committed action, and both committed action and EA were correlated with life satisfaction. This aligns with previous findings (<xref ref-type="bibr" rid="B31">Kashdan et al., 2006</xref>; <xref ref-type="bibr" rid="B8">Chawla and Ostafin, 2007</xref>; <xref ref-type="bibr" rid="B20">Graham et al., 2016</xref>; <xref ref-type="bibr" rid="B58">Valdivia-Salas et al., 2017</xref>; <xref ref-type="bibr" rid="B56">Trindade et al., 2018</xref>; <xref ref-type="bibr" rid="B40">Lucas and Moore, 2020</xref>). On this basis, we further investigated whether committed action mediates the relationships between EA and life satisfaction. In the hypothesized mediation model, EA was the independent variable, committed action was the mediating variable, and life satisfaction was the dependent variable. A mediator model was used to test if committed action mediates the association between EA and life satisfaction.</p>
<p>As shown in <xref ref-type="fig" rid="F1">Figure 1</xref>, (a) EA had a significant negative effect on committed action (&#x03B2; = &#x2013;0.43, SE = 0.03, and <italic>p</italic> &#x003C; 0.001); (b) committed action had a positive effect on life satisfaction (&#x03B2; = 0.33, SE = 0.02, and <italic>p</italic> &#x003C; 0.001); (c) EA had a direct and significant negative effect on life satisfaction (&#x03B2; = &#x2013;0.36, SE = 0.01, and <italic>p</italic> &#x003C; 0.001), which indicated that participants scoring higher on EA tended to score lower on committed action and life satisfaction; and (d) after the mediating variable of committed action was controlled, the influence of EA on life satisfaction was still significant, but was lower than the unmediated effect (&#x03B2; = &#x2013;0.22, SE = 0.01, and <italic>p</italic> &#x003C; 0.001). As shown in <xref ref-type="table" rid="T6">Table 6</xref>, a significant mediating effect of committed action was discovered with an indirect effect of &#x2013;0.060 [SE = 0.008, 95% BCCI (&#x2013;0.077, &#x2013;0.046); <italic>p</italic> &#x003C; 0.001], which accounted for 39.22% of the total influence of EA on life satisfaction.</p>

<title>Discussion</title>
<p>Committed action refers to goal-directed behaviors with flexible persistence and is a core process of psychological flexibility. The development of a Mandarin Chinese version of the CAQ-8 may contribute to the development of an in-depth understanding of committed action in mainland China. This study provides preliminary evidence for the reliability and validity of the Mandarin Chinese version of the CAQ-8. Alpha levels for the CAQ-8 and its subscales ranged from 0.75 to 0.84 and were similar to those of the English CAQ (<xref ref-type="bibr" rid="B14">Gagnon et al., 2017</xref>) and ChCAQ-8 (<xref ref-type="bibr" rid="B16">Gal&#x00E1;n et al., 2019</xref>). The test&#x2013;retest reliability, measured by ICC also found acceptable stability. With regards to the factor structure, CFA supported a two-factor model, as with the original questionnaire, providing initial support for its use in China and cross-culturally more generally.</p>
<p>Regarding convergent validity, the CAQ-8 score was significantly correlated with EA assessed by AAQ-II and present-moment awareness assessed by MAAS, which are theoretically related constructs. In line with expectations, higher levels of committed action were associated with lower levels of EA and higher mindful awareness. Criterion validity was confirmed by correlations between committed action and depression, stress, anxiety, and life satisfaction. The results suggested that higher levels of committed action were correlated with lower levels of mental distress and greater life satisfaction. The results of the hierarchical regression analyses suggest that the CAQ-8 score added incremental variance in addition to AAQ-II and MAAS when predicting depression and life satisfaction, but did not do so for anxiety and stress. One previous study found that low committed action is a predictor of depression (<xref ref-type="bibr" rid="B43">McCracken, 2013</xref>). A previous study found that psychological flexibility was a strong predictor of life satisfaction (<xref ref-type="bibr" rid="B40">Lucas and Moore, 2020</xref>), suggesting that living in accordance with personal values increased life satisfaction. Another recent study found that committed action, as one core component of psychological flexibility, could mitigate the adverse effects of trait health anxiety on mental health during COVID-19 lockdown in Italy (<xref ref-type="bibr" rid="B35">Landi et al., 2020</xref>). There does not appear to be any previous research exploring the effect of committed action on stress. Here, CAQ-8 scores did not contribute significant variance in predicting anxiety or stress. This may be because committed action can occur even in the presence of distress (<xref ref-type="bibr" rid="B43">McCracken, 2013</xref>), such as worry (anxiety) or stress. Besides, CAQ-8, MAAS, and AAQ-II, as measures of related ACT processes, may share a common variance for explaining stress and anxiety.</p>
<p>Overall, these findings suggest that the Mandarin Chinese version of the CAQ-8 is adequate for use in a Chinese university student sample. So, the current study expands the use of the CAQ-8 in a non-clinical population and lays the foundation for future cross-cultural studies.</p>
<p>In addition, these findings extend previous research by exploring the mediating roles of committed action in the association between EA and life satisfaction. The direct impact of EA on life satisfaction is well-established (<xref ref-type="bibr" rid="B48">Palladino et al., 2013</xref>; <xref ref-type="bibr" rid="B20">Graham et al., 2016</xref>; <xref ref-type="bibr" rid="B58">Valdivia-Salas et al., 2017</xref>; <xref ref-type="bibr" rid="B56">Trindade et al., 2018</xref>; <xref ref-type="bibr" rid="B40">Lucas and Moore, 2020</xref>), although the mechanisms are relatively unclear. Here, it appears that committed action partially mediated the effect of EA on life satisfaction. This suggests that being more prone to EA&#x2014;to be unwilling to accept unwanted inner experience&#x2014;is related to the reduced committed action, which, in turn, reduces life satisfaction (<xref ref-type="bibr" rid="B57">Trompetter et al., 2013</xref>). This suggests that being open to unpleasant private experiences and engaging in activities based on personal values and goals are significantly related to greater life satisfaction. Theoretically, the ability to pursue valued goals in the presence of unwanted private events has a positive impact on life satisfaction (<xref ref-type="bibr" rid="B20">Graham et al., 2016</xref>; <xref ref-type="bibr" rid="B21">Graham and Rose, 2017</xref>).</p>
<p>Findings also provide more general support for psychological flexibility theory, which emphasizes the need to pursue valued goals in the context of acceptance to live an ideal life, which would be one way of defining life satisfaction (<xref ref-type="bibr" rid="B13">Diener, 1984</xref>). People engaged in EA may disrupt committed action so, despite avoidance reducing upset in the short term, it increases suffering and generates behavior inflexibility in the long run, thereby preventing the person from engaging in wellbeing enhancing activities (<xref ref-type="bibr" rid="B27">Hayes et al., 1996</xref>). In contrast, committed action includes flexible persistence so that people can adapt actions when goal-directed behavior leads to pain, distress, and failure (<xref ref-type="bibr" rid="B43">McCracken, 2013</xref>).</p>
<p>There are some limitations of the study. First, the sample was comprised of university students. Further studies should be expanded to the general Chinese population and clinical samples. Second, convenience sampling produced a predominantly female sample. Third, the mediation analysis was cross-sectional. A longitudinal design test for mediation effects would be more rigorous and powerful (<xref ref-type="bibr" rid="B9">Cole and Maxwell, 2003</xref>). Fourthly, the measure of life satisfaction used was designed for children and adolescents, which may limit the translation of these results to older groups.</p>

<title>Conclusion</title>
<p>The CAQ-8 (Mandarin) appears to be a promising measurement tool for assessing committed action among a sample of Chinese students, which could also be used in the general population. More generally, the psychological flexibility model and ACT appear to apply in China. Moreover, committed action may partially mediate the association between EA and life satisfaction, suggesting that committed action could play a significant role in explaining how EA is related to life satisfaction.</p>
