Social media addiction (SMA) is the excessive use of social media platforms, resulting in negative consequences for individuals. It is characterized by an uncontrollable urge to use social media, leading to negative effects in human's life. This study aims to construct a mathematical model to conceptualize the transmission dynamics of SMA and explore the underlying mechanisms of this harmful addiction in the framework of fractional derivative. The fundamentals of fractional calculus are listed for examining the model. Equilibrium points are identified, and the reproduction parameter R0 is computed to understand the dynamics of SMA spread. Stability analysis of the equilibria is performed, and the impact of various input parameters is numerically investigated. The existence and uniqueness of the proposed SMA model are demonstrated through simulations, which also study the intricate dynamics with respect to different input factors. To develop effective control strategies, the system's dynamical behavior is examined, and the influence of fractional derivative order on fluctuations is explored. This research offers a range of suggestions aimed at reducing the occurrence of social media addiction.

1. Introduction

Social media and fractional calculus, social media addiction, mathematical model, Caputo-Fabrizio operator, numerical scheme, dynamical behavior internet are specific platforms and websites that facilitate social interactions, content sharing, and networking among users. These platforms typically have features that allow individuals to create profiles, connect with friends, share updates, photos, videos, and engage in conversations and communities [13]. Social media, when utilized properly, can help people develop essential abilities such as information access [4], self-directed learning [5], problem-solving [6], and business, but those who misuse it have a detrimental impact on them [7, 8]. The most important negative impact is social media addiction [8]. In the beginning, social media addiction appears to be safe, similar to addiction to gambling, alcohol, and narcotics, but it is a serious trend that has to be addressed [9]. The individuals who are spending much time on social media such as YouTube, Facebook, Twitter, Instagram, and other such platforms are called social media addicted individuals [6]. Despite the myriad benefits social media offers, it is crucial to exercise responsible usage and remain aware of potential downsides, including privacy issues, information overload, cyberbullying, and the risk of addiction. Signs and symptoms of social media addiction may include compulsive checking, neglecting responsibilities, tolerance, neglecting relationship, disturbance in sleeping, and impact on mental health.

Numerous methods have been presented in academic literature to comprehend various real-world situations [1012]. Social media addiction has emerged as a prominent and pressing problem, garnering significant attention and concern within the academic and scientific community [13]. As a result of this, substantial research on this topic has been done in multiple nations [8, 13] and attracted many researchers. Affinity-based information diffusion in social networks can be analyzed using tools from Lie algebra, particularly through the concept of graph representations. In [14], the authors proposed a dynamical information diffusion model that incorporates the concept of affinity among individuals toward the information being disseminated in social networks. The activities associated with addiction can cause serious issues at home, work, and school which can have a negative impact on society as a whole [3, 4]. Before it has any more negative impacts than what we can now see, this issue needs to be addressed [9, 13]. The easiest approach to do this is to think about how social media addiction will affect your life. Advertising and informational campaigns regarding the harmful consequences of social media are seen as a form of control. The alternative strategy involves employing therapeutic techniques such as disabling notifications [6], setting time limits for social media use [7], deleting apps [15], disconnecting from technology [16], never using a smartphone in bed, and others. It has been acknowledged that there is a high negative impact of social media addiction; moreover, protective policies are required to reduce and manage its influence. Hence, we propose a mathematical model to comprehend the dynamics of social media dissemination, aiming to conceptualize the comprehensive phenomena and forecast potential control strategies that hold the capacity to ameliorate the adverse repercussions arising from social media addiction and foster more conducive usage patterns.

Fractional calculus offers a valuable mathematical framework for modeling complex phenomena, analyzing intricate systems, and providing more accurate descriptions of various natural and engineered systems [1719]. It enables a deeper understanding and improved control of processes with fractional-order dynamics that go beyond the capabilities of traditional integer-order calculus. In literature [20, 21], novel fractional operators were developed that were successfully applied to the simulation of numerous real-world scenarios. Ordinary differential systems are widely recognized as suitable for local systems that are not influenced by external factors. However, conventional differential operators are unable to handle the complexity and crossover behavior of natural phenomena. Fractional calculus have numerous applications in control theory, finance, image processing, electrochemistry, and many other branches of science and engineering. Its ability to describe and analyze systems with non-local, non-linear, and memory-dependent behavior makes it a valuable tool in many scientific, engineering, and mathematical fields. In this study, we will utilize the concept of full memory to interrogate and understand the intricate phenomena of social media addiction. We opt to find out the most sensitive factors of the system and suggest to the concerned officials.

We have decided to propose a mathematical model for SMA using Caputo-Fabrizio of order ϖ∈(0, 1] as a consequence of the study mentioned above. The remaining article is structured as follows: Section 2 includes the fundamental results and claims of the fractional-calculus. In Section 3, we construct a fractional Caputo-Fabrizio (CF) derivative-based model of social media addiction (SMA). We examined the equilibriums and ascertained the reproduction number for the recommended system in Section 4. Existence and uniqueness of the solution of our system are examined with the use of fixed-point theory in Section 5. We also established a numerical framework in Section 5 to examine how various input factors affect the system's dynamics. The study's conclusion is provided in Section 6.

2. Fractional concepts

In this study, the rudimentary results of Caputo-Fabrizio (CF) fractional derivative will be presented for the analysis of the recommended model. The basic concepts are given below.

Definition 2.1. Let a function Y(t)H1(c1,c2) then its CF fractional derivative [21] is given as

Dtϖ(Y(t))=U(ϖ)1ϖc1tY(x)exp[ϖtx1ϖ]dx,    (1)

where c2 > c1 and 𝔘(τ) represents the normality [21] such that 0 ≤ ϖ ≥ 1. If jH1(c1,c2), then we can write

Dtϖ(Y(t))=ϖG(ϖ)1ϖc1t(Y(t)Y(x))exp[ϖtx1ϖ]dx.    (2)

Remark 2.1. If φ=1-ϖϖ[0,) and ϖ=11+φ[0,1], then Equation (2) states that

Dtϖ(Y(t))=N(φ)φc1tY(x)e[txφ]dx, N(0)=N()=1.    (3)

Moreover, we can write

limφ01φexp[txφ]=δ(xt).    (4)

Definition 2.2. [22]. The integral in fractional framework for Y is stated below as

Itϖ(Y(t))=2(1-ϖ)(2-ϖ)G(ϖ)Y(t)+2ϖ(2-ϖ)G(ϖ)0tY(u)du,t0.    (5)

in which the order of fractional derivative is represented by ϖ with the restriction that 0 < ϖ < 1.

Remark 2.2. On the basis of Definition 2.2, we can write

2(1-ϖ)(2-ϖ)𝔘(ϖ)+2ϖ(2-ϖ)𝔘(ϖ)=1,    (6)

which states that 𝔘(ϖ)=22-ϖ, 0 < ϖ < 1. By utilizing (6) through the study [22], we obtained the following result:

Dtϖ(Y(t))=11ϖ0tY(x)exp[ϖtx1ϖ]dx,    (7)

where fractional order is ϖ with 0 < ϖ < 1.

3. Formulation of the non-integer model

In this formulation, we classified the humans population into five subclasses symbolized in the following manner; 𝔖 represents the susceptible individuals, exposed individuals are represented by 𝔈, addicted individuals are indicated by 𝔄, recovered class of individuals are denoted by ℜ while the individuals not permanently addicted with SMA are represented by 𝔔.

The susceptible class grows due to the recruitment of individuals at the rate of α. Moreover, the term ωξℜ increases the population, while the terms ϕθ𝔄𝔖 and (μ+ρ)𝔖 lowers the population where ω is the proportion of recovered individuals that were susceptible to SMA, ξ is the transmission rate from the recovered class, ϕ is the rate at which addiction is transmitted to individuals, θ is the rate at which susceptible individuals came in contact with addicted individuals, μ represents the susceptible individuals that were not addicted to social media, and ρ is the natural fatality rate. Therefore, the susceptible individuals class can be stated as

d𝔖dt=α+ωξ-ϕθ𝔄𝔖-(μ+ρ)𝔖.

The exposed class increases due to ϕθ𝔄𝔖, while the term (τ + ρ)𝔈 decreases the population, where τ is the treatment rate of addicted individuals. Thus, the exposed class is mathematically represented as

d𝔈dt=ϕθ𝔄𝔖-(τ+ρ)𝔈.

The term υτ𝔈 increases the addicted class population, while (ρ + ζ + ψ)ℜ lowers the population, where ζ is the progression rate from the addicted to the recovered class and ψ is the fatality rate due to SMA. Hence, the addicted class is mathematically given as

d𝔄dt=υτ𝔈-(ρ+ζ+ψ)𝔄.

The recovered class grows due to τ𝔈 and ζ𝔄, while it decreases due to υτ𝔈 and (ρ+ξ)ℜ. Thus, the recovered class is represented by

ddt=(1-υ)τ𝔈+ζ𝔄-(ρ+ξ).

The class of not permanently addicted individuals increases by μ𝔖 and ξℜ, while it decreases due to ωξℜ and ρθ. Therefore, the class of individuals permanently not addicted with social media is stated as

d𝔔dt=μ𝔖+(1-ω)ξ-ρ𝔔.

Thus, the above-stated assumptions lead us to derive an ODE model for SMA, which is stated below as

{dSdt=α+ωξϕθAS(μ+ρ)S,dEdt=ϕθAS(τ+ρ)E,dAdt=υτE(ρ+ζ+ψ)A,ddt=(1υ)τE+ζA(ρ+ξ),dQdt=μS+(1ω)ξρQ,    (8)

having state-variables

𝔖(0)=𝔖0,𝔈(0)=𝔈0,𝔄(0)=𝔄0,(0)=0,𝔔(0)=𝔔0 and  𝔑(0)=𝔑0.

The total population is stated by

𝔑(t)=𝔖(t)+𝔈(t)+𝔄(t)+(t)+𝔔(t).

In particular, the realistic problem can benefit greatly from the use of fractional calculus. It has been demonstrated that fractional frameworks can more precisely depict the dynamics of real-world problems than traditional integer-order derivatives. The fractional framework equivalent to the aforementioned SMA model is stated below:

{0CFDtϖS=α+ωξϕθAS(μ+ρ)S,0CFDtϖE=ϕθAS(τ+ρ)E,0CFDtϖA=υτE(ρ+ζ+ψ)A,0CFDtϖ=(1υ)τE+ζA(ρ+ξ),0CFDtϖQ=μS+(1ω)ξρQ,    (9)

where CF fractional operator order is ϖ. The parameters of the model are described in Table 1 in detail. The following result provides the SMA fractional system positive invariant region stated as follows.

TABLE 1
www.frontiersin.org

Table 1. Detail descriptions of the parameters of the model used in the study.

Theorem 3.1. The set Γ will be a positive invariant for system (9) of SMA if Γ={(𝔖,𝔈,𝔄,,𝔔)R+5:0<𝔑(t)αρ}.

Proof Let us consider any solution of the system (9) for the set (𝔖, 𝔈, 𝔄, ℜ, 𝔔). Since we know that

𝔑=𝔖+𝔈+𝔄++𝔔.

Then adding the equations of system (9), we get that

d𝔑dt=α-ρ𝔑-ψ𝔄.    (10)

If no death occurs due to SMA, then Equation (10) can be rewritten as

d𝔑dt=α-ρ𝔑.    (11)

Then, 𝔑(t)𝔑(0)exp-ρt+αρ(1-exp-ρt) is the solution of Equation (11), as t → ∞, then 𝔑(t)αρ. Therefore, the set Γ={(𝔖,𝔈,𝔄,,𝔔)R+5:0<𝔑(t)αρ} is a positive invariant of system (9).

4. Analysis of fractional dynamics

Now, we will examine the steady-state and stability of the recommended fractional model (9) of SMA. First, we investigate the system's addiction-free equilibrium, represented by 𝔈0. Consider the fractional model of SMA described above in steady states without addiction. Thus, we get the SMA addiction-free equilibrium as follows:

𝔈0=(α(ρ+μ),0,0,0,αμρ(ρ+μ)).

For a reproduction parameter, we proceed as follows:

F=[ϕθ𝔄𝔖00],   V=[(τ+ρ)𝔈-υτ𝔈+(ρ+ζ+ψ)𝔄-(1-υ)τ𝔈-ζ𝔄+(ρ+ξ)].

Evaluating Jacobian of matrix F and V at 𝔈0, we get the following:

Ϝ=[oϕαθμ+ρ0oooooo],    (12)
V=[τ+ρ00-υτρ+ζ+ψ0-(1-υ)-ζρ+ξ].    (13)

Hence, we get that Ξ(ϜV-1)=ϕαυτθ(μ+ρ)(τ+ρ)(ρ+ζ+ψ) , which gives the reproduction number as

R0=ϕαυτθ(μ+ρ)(τ+ρ)(ρ+ζ+ψ).

Theorem 4.1. If R0 < 1, then the system (9) addiction-free equilibrium is locally asymptotically stable and unstable otherwise.

Proof To get the required results, first we will evaluate the Jacobian matrix of the system (9) at 𝔈0 as follows:

J𝔈0=[-(μ+ρ)0-ϕαθμ+ρωξ00-(τ+ρ)ϕαθμ+ρ000υτ-(ζ+ψ+ρ)000(1-υ)τζ-(ξ+ρ)0μ00(1-ω)ξ-ρ],    (14)

The eigenvalues of the matrix J𝔈0 are

-ρ,-(μ+ρ),-(ξ+ρ),

and the remaining two eigenvalues will be obtained by solving the below stated quadratic equation:

λ2+P1λ+P2=0,

where P1=ζ+ψ+τ+2ρ and P2=(τ+ρ)(ζ+ψ+ρ)-ϕαυτθμ+ρ.

To check that the roots of the quadratic equation are negative, we utilize the Routh-Hurwitz criteria which state that the Equation (14) has negative real roots if P1>0,P2>0,  and  P1P2>0. Obviously, P1>0, we may write P2 in the following form:

P2=(τ+ρ)(ζ+ψ+ρ)(1-ϕαυτθ(μ+ρ)(τ+ρ)(ζ+ψ+ρ)),P2=(τ+ρ)(ζ+ψ+ρ)(1-𝔈0),

which shows that P2>0 if 𝔈0 < 1. Therefore, we proved that if 𝔈0 < 1, then the SMA addiction-free equilibrium is locally asymptotically stable.

The equilibrium point with addiction can be obtained by supposing Equation (9) equal to zero as follows:

{0=α+ωξϕθAS(μ+ρ)S,0=ϕθAS(τ+ρ)E,0=υτE(ρ+ζ+ψ)A,0=(1υ)τE+ζA(ρ+ξ),0=μS+(1ω)ξρQ,    (15)

and on further simplification, we get that

𝔖=(ρ+τ)(ρ+ζ+ψ)υϕτθ,

𝔈=(ζ+ψ+ρ)1ϕτυθ,

𝔄=1ϕθ2,

=(υρ+υψ-ζ-ρ-ψ)[αυϕτθ-(ρ+τ)(μ+ρ)(ρ+ζ+ψ)]υϕθ2,

𝔔=μ𝔖+(1-ω)ξρ.

where

1=αυτϕθ(ξ+ρ)-(μ+ρ)(τζξ+τζρ+ζξρ)-(ψ+ρ)(μ+ρ)(ρ+τ)(ρ+ξ)-ζρ2(ρ+μ),

2 = υτωξ(ψ+ρ)−τωξ(ζ+ξ+ρ) + (ζ+ψ+ρ)(τ+ρ)(ξ+ρ).

Theorem 4.2. If R0 > 1, then the fractional system (9) has locally asymptotically stable endemic steady-state.

To analyze the local asymptotic stability of the endemic equilibrium in a dynamical system, we typically perform linear stability analysis. This involves linearizing the system's equations around the endemic equilibrium point and examining the eigenvalues of the resulting Jacobian matrix. The local asymptotic stability is determined by the signs of the real parts of the eigenvalues. If all eigenvalues have negative real parts, then the endemic equilibrium is locally asymptotically stable. This means that small perturbations around the equilibrium point will decay over time, and the system will ultimately return to the endemic equilibrium after experiencing minor disturbances.

5. Analysis of the solutions

In this study, we concentrate on the examination of the recommended SMA fractional system solutions. The presence of a solution of system (9) will be investigated using the fixed-point theory. We move forward in the following manner:

{ S(t)S(0)=0CFItϖ{α+ωξϕθAS(μ+ρ)S},E(t)E(0)=0CFItϖ{ϕθAS(τ+ρ)E},A(t)A(0)=0CFItϖ{υτE(ρ+ζ+ψ)A},(t)(0)=0CFItϖ{(1υ)τE+ζA(ρ+ξ)},Q(t)Q(0)=0CFItϖ{μS+(1ω)ξρQ}.    (16)

Utilizing the similar approach listed in [22], we get the following result

𝔖(t)-𝔖(0)=2(1-ϖ)(2-ϖ)G(ϖ){α+ωξ-ϕθ𝔄𝔖-(μ+ρ)𝔖}                           +2ϖ(2-ϖ)G(ϖ)                           0t{α+ωξ-ϕθ𝔄𝔖-(μ+ρ)𝔖}dy,𝔈(t)-𝔈(0)=2(1-ϖ)(2-ϖ)G(ϖ){ϕθ𝔄𝔖-(τ+ρ)𝔈}                           +2ϖ(2-ϖ)G(ϖ)0t{ϕθ𝔄𝔖-(τ+ρ)𝔈}dy,𝔄(t)-𝔄(0)=2(1-ϖ)(2-ϖ)G(ϖ){υτ𝔈-(ρ+ζ+ψ)𝔄}                           +2ϖ(2-ϖ)G(ϖ)0t{υτ𝔈-(ρ+ζ+ψ)𝔄}dy,(t)-(0)=2(1-ϖ)(2-ϖ)G(ϖ){(1-υ)τ𝔈+ζ𝔄-(ρ+ξ)}                           +2ϖ(2-ϖ)G(ϖ)                           0t{(1-υ)τ𝔈+ζ𝔄-(ρ+ξ)}dy,𝔔(t)-𝔔(0)=2(1-ϖ)(2-ϖ)G(ϖ){μ𝔖+(1-ω)ξ-ρ𝔔}                           +2ϖ(2-ϖ)G(ϖ)0t{μ𝔖+                           (1-ω)ξ-ρ𝔔}.    (17)

Moreover, we can write

{ L1(t,S)=α+ωξϕθAS(μ+ρ)S,L2(t,E)=ϕθAS(τ+ρ)E,L3(t,A)=υτE(ρ+ζ+ψ)A,L4(t,)=(1υ)τE+ζA(ρ+ξ),L5(t,Q)=μS+(1ω)ξρQ.    (18)

Theorem 5.1. If the condition 0ϕθA+μ+ρ<1 holds then the kernels 𝔏1, 𝔏2, 𝔏3, 𝔏4, and 𝔏5 satisfies the condition of Lipschitz and contraction.

Proof 5.1 To obtain the required result, we proceed in the following way:

𝔏1(t,𝔖)-𝔏1(t,𝔖1)=-ϕθ𝔄{𝔖(t)-𝔖(t1)}-μ{𝔖(t)-𝔖(t1)}-ρ{𝔖(t)-𝔖(t1)}.    (19)

Taking norm on Equation (19) and further evaluating, we get

||𝔏1(t,𝔖)-𝔏1(t,𝔖1)||||ϕθ𝔄{𝔖(t)-𝔖(t1)}||+                                                     μ||{𝔖(t)-𝔖(t1)}||                                                     +ρ||{𝔖(t)-𝔖(t1)}||                                              ϕθ||𝔄||||{𝔖(t)-𝔖(t1)}||+                                                     μ||{𝔖(t)-𝔖(t1)}||                                                     +ρ||{𝔖(t)-𝔖(t1)}||                                              ϕθA||{𝔖(t)-𝔖(t1)}||+                                                     μ||{𝔖(t)-𝔖(t1)}||                                                     +ρ||{𝔖(t)-𝔖(t1)}||                                              (ϕθA+μ+ρ)||                                                     {𝔖(t)-𝔖(t1)}||.    (20)

Let Ϝ1=(ϕθA+μ+ρ), where ||𝔄||A due to boundedness, we achieve the following result

||𝔏1(t,𝔖)-𝔏1(t,𝔖1)||Ϝ1||𝔖(t)-𝔖(t1)||.    (21)

Hence, the Lipschitz condition is obtained for 𝔏1, from the condition 0(ϕθA+μ+ρ)<1, we can also get the contraction. Similarly, the Lipschitz condition for 𝔏2, 𝔏3, 𝔏4, and 𝔏5 can be derived as

||𝔏2(t,𝔈)-𝔏2(t,𝔈1)||Ϝ2||𝔈(t)-𝔈(t1)||,||𝔏3(t,𝔄)-𝔏3(t,𝔄1)||Ϝ3||𝔄(t)-𝔄(t1)||,||𝔏4(t,)-𝔏4(t,1)||Ϝ4||(t)-(t1)||,||𝔏5(t,𝔔)-𝔏5(t,𝔔1)||Ϝ5||𝔔(t)-𝔔(t1)||.    (22)

After simplifying Equation (17), we get

{ S(t)=S(0)+2(1ϖ)(2ϖ)G(ϖ)L1(t,S)+2ϖ(2ϖ)G(ϖ)0t(L1(y,S))dy,E(t)=E(0)+2(1ϖ)(2ϖ)G(ϖ)L2(t,E)+2ϖ(2ϖ)G(ϖ)0t(L2(y,E))dy,A(t)=A(0)+2(1ϖ)(2ϖ)G(ϖ)L3(t,A)+2ϖ(2ϖ)G(ϖ)0t(L3(y,A))dy,(t)=(0)+2(1ϖ)(2ϖ)G(ϖ)L4(t,)+2ϖ(2ϖ)G(ϖ)0t(L4(y,))dy,Q(t)=Q(0)+2(1ϖ)(2ϖ)G(ϖ)L5(t,Q)+2ϖ(2ϖ)G(ϖ)0t(L5(y,Q))dy.     (23)

moreover, we obtain that

{Sq(t)=2(1ϖ)(2ϖ)G(ϖ)L1(t,S(q1))+2ϖ(2ϖ)G(ϖ)0t(L1(y,S(q1)))dy,Eq(t)=2(1ϖ)(2ϖ)G(ϖ)L2(t,E(q1))+2ϖ(2ϖ)G(ϖ)0t(L2(y,E(q1)))dy,Aq(t)=2(1ϖ)(2ϖ)G(ϖ)L3(t,A(q1))+2ϖ(2ϖ)G(ϖ)0t(L3(y,A(q1)))dy,q(t)=2(1ϖ)(2ϖ)G(ϖ)L4(t,(q1))+2ϖ(2ϖ)G(ϖ)0t(L4(y,(q1)))dy,Qq(t)=2(1ϖ)(2ϖ)G(ϖ)L5(t,Q(q1))+2ϖ(2ϖ)G(ϖ)0t(L5(y,Q(q1)))dy,    (24)

initial values are given as

𝔖0(t)=𝔖(0),𝔈(t)=𝔈(0),𝔄0(t)=𝔄(0),0(t)=(0),𝔔0(t)=𝔔(0).

We get the difference terms in the following manner:

χ1q(t)=Sq(t)S(q1)(t)=             2(1ϖ)(2ϖ)G(ϖ)(L1(t,S(q1))L1(t,S(q2)))             +2ϖ(2ϖ)G(ϖ)0t(L1(y,S(q1))           L1(y,S(q2)))dy,χ2q(t)=Eq(t)E(q1)(t)=2(1ϖ)(2ϖ)G(ϖ)(L1(t,E(q1))             L1(t,E(q2)))           +2ϖ(2ϖ)G(ϖ)0t(L1(y,E(q1))             L1(y,E(q2)))dy,χ3q(t)=Aq(t)A(q1)(t)=2(1ϖ)(2ϖ)G(ϖ)(L1(t,A(q1))             L1(t,A(q2)))             +2ϖ(2ϖ)G(ϖ)0t(L1(y,A(q1))             L1(y,A(q2)))dy,χ4q(t)=q(t)(q1)(t)=2(1ϖ)(2ϖ)G(ϖ)(L1(t,(q1))             L1(t,(q2)))             +2ϖ(2ϖ)G(ϖ)0t(L1(y,(q1))             L1(y,(q2)))dy,χ5q(t)=Qq(t)Q(q1)(t)=2(1ϖ)(2ϖ)G(ϖ)(L1(t,Q(q1))             L1(t,Q(q2)))             +2ϖ(2ϖ)G(ϖ)0t(L1(y,Q(q1))             L1(y,Q(q2)))dy.    (25)

Observing that

{Sq(t)=r=1qχ1r(t),Eq(t)=r=1qχ2r(t),Aq(t)=r=1qχ3r(t),q(t)=r=1qχ4r(t),Qq(t)=r=1qχ5r(t).    (26)

Similarly, we obtain

||χ1q(t)||=||Sq(t)S(q1)(t)||=                         2(1ϖ)(2ϖ)G(ϖ)(L1(t,S(q1))L1(t,S(q2)))                         +2ϖ(2ϖ)G(ϖ)0t(L1(y,S(q1))                         L1(y,S(q2)))dy.    (27)

Equation (27) states that

Sq(t)S(q1)(t)2(1ϖ)(2ϖ)G(ϖ)(L1(t,S(q1))                                                L1(t,S(q2)))                                                +2ϖ(2ϖ)G(ϖ)0t(L1(y,S(q1))                                                L1(y,S(q2)))dy,    (28)

which gives the following equation

||𝔖q(t)-𝔖q-1(t)||2(1-ϖ)(2-ϖ)G(ϖ)Ϝ1||𝔖(q-1)-𝔖(q-2)||                                           +2ϖ(2-ϖ)G(ϖ)Ϝ1                                           ×0t||𝔖(q-1)-𝔖(q-2)||dy.    (29)

Additionally,

||χ1q(t)||2(1-ϖ)(2-ϖ)G(ϖ)Ϝ1||χ1(q-1)(t)||                      +2ϖ(2-ϖ)G(ϖ)Ϝ10t||χ1(q-1)(y)||dy.    (30)

In similar manner, we get the following results

||χ2q(t)||2(1-ϖ)(2-ϖ)G(ϖ)Ϝ2||χ2(q-1)(t)||                      +2ϖ(2-ϖ)G(ϖ)Ϝ20t||χ2(q-1)(y)||dy,||χ3q(t)||2(1-ϖ)(2-ϖ)G(ϖ)Ϝ3||χ3(q-1)(t)||                      +2ϖ(2-ϖ)G(ϖ)Ϝ30t||χ3(q-1)(y)||dy,||χ4q(t)||2(1-ϖ)(2-ϖ)G(ϖ)Ϝ4||χ4(q-1)(t)||                      +2ϖ(2-ϖ)G(ϖ)Ϝ40t||χ4(q-1)(y)||dy,||χ5q(t)||2(1-ϖ)(2-ϖ)G(ϖ)Ϝ5||χ5(q-1)(t)||                      +2ϖ(2-ϖ)G(ϖ)Ϝ50t||χ5(q-1)(y)||dy.    (31)

Theorem 5.2. If we can find t0 such that it satisfies the following condition

2(1-ϖ)(2-ϖ)G(ϖ)Ϝ1+2ϖ(2-ϖ)G(ϖ)Ϝ1t0<1,

then, the proposed fractional system (9) have an exact coupled-solutions.

Proof 5.2 Since the Lipschitz condition holds and 𝔖(t), 𝔈(t), 𝔄(t), ℜ(t), and 𝔔(t) are bounded. Then, Equations (30) and (31) implies

χ1q(t)||Sq(0)||[(2(1ϖ)(2ϖ)G(ϖ)Ϝ1)+                         (2ϖ(2ϖ)G(ϖ)Ϝ1t)]q,χ2q(t)||Eq(0)||[(2(1ϖ)(2ϖ)G(ϖ)Ϝ2)+                         (2ϖ(2ϖ)G(ϖ)Ϝ2t)]q,χ3q(t)||Aq(0)||[(2(1ϖ)(2ϖ)G(ϖ)Ϝ3)+                         (2ϖ(2ϖ)G(ϖ)Ϝ3t)]q,χ4q(t)||q(0)||[(2(1ϖ)(2ϖ)G(ϖ)Ϝ4)+                         (2ϖ(2ϖ)G(ϖ)Ϝ4t)]q,χ5q(t)||Qq(0)||[(2(1ϖ)(2ϖ)G(ϖ)Ϝ5)+                         (2ϖ(2ϖ)G(ϖ)Ϝ5t)]q.    (32)

Hence, the continuity and existence of the solution are proved. In order to prove that the above mentioned is a solution of system (9), we take the following steps:

𝔖(t)-𝔖(0) = 𝔖q(t)-Z1q(t),𝔈(t)-𝔈(0) = 𝔈q(t)-Z2q(t),𝔄(t)-𝔄(0) = 𝔄q(t)-Z3q(t),(t)-(0) = q(t)-Z4q(t),𝔔(t)-𝔔(0) = 𝔔q(t)-Z5q(t).    (33)

Now consider

q(t)=||2(1ϖ)(2ϖ)G(ϖ)(L1(t,Sq)L1(t,S(q1)))+                      2ϖ(2ϖ)G(ϖ)×                      0t(L1(y,Sq)L1(y,S(q1)))dy||,                2(1ϖ)(2ϖ)G(ϖ)(L1(t,Sq)(L1(t,S(q1)))+                      2ϖ(2ϖ)G(ϖ)×                      0t||(L1(y,S)L1(y,S(q1)))||dy,                2(1ϖ)(2ϖ)G(ϖ)Ϝ1SS(q1)+                      2ϖ(2ϖ)G(ϖ)Ϝ1SS(q1)t.    (34)

Moreover, we have

Z1q(t)(2(1ϖ)(2ϖ)G(ϖ)                +2ϖ(2ϖ)G(ϖ)t)q+1Ϝ1q+1a.    (35)

At time t0, we have

Z1q(t)(2(1ϖ)(2ϖ)G(ϖ)+2ϖ(2ϖ)G(ϖ)t0)q+1Ϝ1q+1a.    (36)

Proceeding in the same manner and utilizing (36), we obtain

||Z1q(t)||0,   q.

Moving in the same manner as stated above, we get that Z2q(t),Z3q(t),Z4q(t),Z5q(t), and Z6q(t) approaches to 0 as q approaches ∞.

Theorem 5.3. If the below stated condition holds

(12(1ϖ)(2ϖ)G(ϖ)Ϝ12ϖ(2ϖ)G(ϖ)Ϝ1t)>0,    (37)

then the solution of system (9) will be unique.

Proof 5.3 To prove the required result, let the above (37) holds true and (𝔖1(t), 𝔈1(t), 𝔄1(t), ℜ1(t), 𝔔1(t)) is any other solution of system (9), then

𝔖(t)-𝔖1(t)=2(1-ϖ)(2-ϖ)G(ϖ)(𝔏1(t,𝔖)-𝔏1(t,𝔖1))+                            2ϖ(2-ϖ)G(ϖ)×                            0t(𝔏1(y,𝔖)-𝔏1(y,𝔖1)) dy.    (38)

Taking norm on (38), we obtain

||𝔖(t)-𝔖1(t)||2(1-ϖ)(2-ϖ)G(ϖ)||𝔏1(t,𝔖)-𝔏1(t,𝔖1)||+                                  2(2-)G()×0t||𝔏1(y,Sh)-+                                  𝔏1(y,S1h)||dy.    (39)

Hence, by using Lipschitz condition, we get the following result:

||𝔖(t)-𝔖1(t)||2(1-ϖ)(2-ϖ)G(ϖ)Ϝ1||𝔖(t)-𝔖1(t)||+                                  2ϖ(2-ϖ)G(ϖ)×                                  0tϜ1||𝔖(t)-𝔖1(t)||dy.    (40)

This shows that

S(t)S1(t)(12(1ϖ)(2ϖ)G(ϖ)Ϝ12ϖ(2)G(ϖ)Ϝ1t)0    (41)

Moreover, we have

(12(1ϖ)(2ϖ)G(ϖ)Ϝ12ϖ(2ϖ)G(ϖ)Ϝ1t)>0,

and the above inequality 41 implies that

||𝔖(t)-𝔖1(t)||=0,

which gives

𝔖(t)=𝔖1(t).    (42)

Similarly, we get the following results

𝔈(t)=𝔈1(t),  𝔄(t)=𝔄1(t),
(t)=1(t),  𝔔(t)=𝔔1(t).

Hence, the fractional system (9) of social media addiction has a unique solution.

In the upcoming subsection, we will present a numerical scheme to visualize the solution pathways of the proposed model. We will perform different numerical simulations to show the variation in the system with different values of input factors.

5.1. Numerical scheme for the system

In this study, our objective is to evaluate the significance of input factors on the output of the proposed fractional system through various simulations. The primary goal is to gain insights into the critical parameters driving the recommended dynamics. First, we provide the numerical solution for the Caputo-Fabrizio model (6) using the scheme introduced in reference [23]. The numerical scheme consists of the following steps:

𝔖(t)-𝔖(0)=(1-ϖ)D(ϖ)G1(t,𝔖)+ϖD(ϖ)0tG1(η,𝔖)dη.    (43)

For t = tn+1, n = 0, 1, 2, ..., we have

𝔖(tn+1)-𝔖0=1-ϖD(ϖ)G1(tn,𝔖n)+ϖD(ϖ)0tn+1G1(t,𝔖)dt.    (44)

The expression for the difference between successive terms is

𝔖n+1-𝔖n=1-ϖD(ϖ){G1(tn,𝔖n)-G1(tn-1,𝔖n-1)}+ϖD(ϖ)tntn+1G1(t,𝔖)dt.    (45)

The function G1(t,𝔖) is approximated in the time interval [tm, t(m+1)] through the interpolation polynomial as follows:

Pm(t)G(tm,ym)h(t-tm-1)-G(tm-1,ym-1)h(t-tm),    (46)

in which h = tmtm−1. Using the above approximation, the integral in (45) can be calculated as

tntn+1G1(t,𝔖)dt=tntn+1G1(tn,𝔖n)h(t-tn-1)-                                        G1(tn-1,𝔖n-1)h(t-tn)dt                                        =3h2G1(tn,𝔖n)-                                        h2G1(tn-1,𝔖n-1).    (47)

Thus, we obtained the following:

Sn+1=Sn+(1ϖD(ϖ)+3h2D(ϖ))G1(tn,Sn)(1ϖD(ϖ)+ϖh2D(ϖ))G1(tn1,Sn1).    (48)

Similarly, we can extend the approach to calculate for other compartments within the system. The numerical scheme described above is employed to obtain the numerical results. Additionally, we make assumptions for the initial values of state-variables and input parameters to facilitate the computations. The outcome of the most sensitive scenario will be proposed to relevant authorities as a preventive measure against social media addiction.

In the first scenario presented in Figures 13, we illustrated the time series of the exposed, addicted, and recovered class with different values of fractional parameter. We assumed the value of the fractional order to be 1.0, 0.9, and 0.8 in the first simulation shown in Figure 1, 0.6, 0.7, and 0.8 in the second simulation represented in Figure 2, and 0.4, 0.5, and 0.6 in the third simulation demonstrated in Figure 3. It has been observed that the fractional order significantly contribute to the proposed dynamics and can lower exposed and addicted individuals in the society by lowering the fractional parameter. In these figures, the arrows indicate that decreasing the fractional parameter leads to a reduction in the number of exposed and addicted individuals within the society. Second, we checked the influence of the contact rate of addicted to the susceptible individuals presented in Figure 4. In this simulation, the contact rate ϕ is taken to be 0.255, 0.355, and 0.455. Finally, we presented the influence of the input parameters ρ and ξ in Figures 5, 6, respectively. The value of ρ is assumed to be 0.221, 0.321, and 0.421, while the value of ξ is considered to be 0.046, 0.056, and 0.066. The role of these parameters has been visualized on the time series of exposed, addicted, and recovered individuals of the system. Our analysis predicts that how the input factors influence the output of the system of social media addiction.

It is essential to recognize that while social media can offer many benefits, excessive and uncontrolled use can lead to addiction and negative effects. Individuals should be aware of their social media habits and take necessary steps to maintain a healthy balance between their online and offline lives. If someone suspects they or someone they know is struggling with social media addiction, seeking support from mental health professionals or support groups can be beneficial.

6. Conclusion

The addiction to social media is a significant concern due to its potential adverse effects on various aspects of individuals' lives, such as their social interactions, daily activities, and overall health. Therefore, it is imperative to investigate the influence of different factors on social media addiction. In this study, we constructed a mathematical model for social media addiction using the Caputo-Fabrizio derivative, a fractional calculus approach. To examine the dynamics of the proposed model, we utilized basic results from fractional theory. The model's equilibrium points were analyzed, and the reproduction parameter was determined, denoted as R0. We demonstrated that the equilibrium point representing an addiction-free state is locally asymptotically stable when R0 < 1 and unstable under other conditions. We have shown the existence and uniqueness of the solution of the recommended model of social media addiction. For analyzing the system's time series behavior, we employed a numerical scheme. Through numerical analysis, we illustrated the dynamical behavior of the social media addiction model under various parameter settings. This allowed us to conceptualize how various input parameters can influence the dynamics of social media addiction. In particular, we observed how different factors contribute to the development and progression of social media addiction. The research outcomes provide valuable insights for public health interventions aimed at preventing social media addiction. We predicted crucial scenarios that could lead to severe addiction and recommended key factors that can be targeted to mitigate the risk of addiction. By understanding the dynamics of social media addiction through our model, policymaker professionals can devise effective strategies to promote healthy social media usage and safeguard individuals from the detrimental effects of excessive social media engagement.
