Distress tolerance is the ability to endure and manage negative emotional states, often leading to behaviors aimed at relief [1]. It is a meta-emotional construct with four dimensions: (1) tolerability and aversiveness, (2) appraisal and acceptability, (3) attention absorption and disruption, and (4) emotion regulation [1]. Distress tolerance is a higher-level concept that influences many elements of mood and behavior control. Gross (1998) identified five points for emotion regulation, categorizing them as four antecedent regulations and one response-oriented regulation [2]. The antecedent-focused regulating is manifested in approaches to selection and modification of the situations, attention deployment, and cognitive changes. The response-focused regulation involves managing emotional changes through behavior, such as suppressing emotion or using substances to dampen feelings. Distress tolerance influences the strategies used to manage affect and affects the regulation of behavior by emotional processes [1].
Distress tolerance is linked to the development and maintenance of psychopathological symptoms, such as substance use as an emotion-based coping strategy [3]. Moreover, the construct of distress tolerance has been used in reference to affect regulation. In Linehan’s Dialectic behavioral theory, this difficulty in tolerating distress stems from a mix of behavioral factors interacting with the social environment. This lack of tolerance can lead to perceiving distress as overwhelming, resulting in actions to ease the discomfort. Consequently, one’s ability to cope with distress greatly influences how emotions are regulated. Moreover, an individual’s resistance to accepting distress as a part of life can worsen their suffering by controlling how they interpret and respond to emotions [4]. This can make managing these emotions more challenging due to their perceived intensity and unpleasantness. Similarly, research on Acceptance and Commitment Therapy (ACT) underscores the impact of avoiding or suppressing emotions. ACT promotes acknowledging and embracing these emotions rather than pushing them suggesting that this approach offers valuable benefits for adaptation. It supports people in making changes, in their behavior by facing and dealing with emotions instead of ignoring them [5]. Moreover, Depression, pots-traumatic stress disorder (PTSD) [6], and eating disorders [7] are among the conditions that distress tolerance is associated with. Low distress tolerance has been observed in impulsive behaviors [8]. This construct is linked to factors such as ambiguity, intolerance of uncertainty, uneasiness, and frustration [9]. Considering these pertinent clinical implications, distress tolerance assessment can be significant in evaluating the risk of psychological difficulties in relevance to the inaptitude to manage negative emotional states, both before and during the treatment of various mental disorders.
Measurement of the distress tolerance construct
Limited evaluation techniques are available to examine the perceived capacity to manage emotionally distressing situations [10]. Measurement has usually focused on concepts linked to handling distress, such as avoiding experiences [11, 12]. Alternatively, studies have used experiments to see how long people endure emotionally challenging activities [13]. Moreover, the field of intelligence has delved into mood acceptance, nonetheless, this was not particularly focused on emotional distress [14]. One of the most widely recognized tools for evaluating distress tolerance is the Distress Tolerance Scale (DTS) created by Simons and Gaher [1], which was later shortened to only four items (i.e., the Distress Tolerance Scale-Short Form, DTS-SF) [15].
The 15-item DTS
It is composed of 15 items divided into four subscales, which are (1) appraisal of and acceptability of emotions (e.g., “My feelings of distress or being upset are not acceptable”), (2) the ability to tolerate negative emotional states (e.g., “Feeling distressed or upset is unbearable to me”), (3) absorption which explains the intensity of the attention an individual hold towards a negative emotion and how absorbing this state becomes (e.g., “My feelings of distress are so intense that they completely take over”) and (4) regulation which is the cognitive or behavioral strategy that individuals utilize to regulate themselves (e.g., “When I feel distressed or upset, I must do something about it immediately”) [1]. Each item can be rated on a 5-point scale ranging from 1 (Strongly agree) to 5 (Strongly disagree). Low scores represent low distress tolerance, while high scores represent high distress tolerance. Several studies have validated the four-factor domains and the psychometric properties of the DTS instrument [9, 16]. The higher-order scale showed good internal consistency (α = .82–.85), while the lower-order scales had adequate consistency (α = .70–.84) [1]. The 15-item DTS showed good convergent and discriminant validity. It was positively correlated with positive affectivity (r = .26) and negatively correlated with negative affectivity (r = − .59). It also showed significant positive correlations with negative mood regulation expectancies (r = .54) and general mood acceptance (r = .47), but less so with mood typicality (r = .17) [1]. Test-retest reliability of the 15-item DTS was supported, where over a six-month interval, the DTS showed temporal stability with an Interclass Correlation Coefficient of .61 [1]. Various studies have compared the DTS to assessment tools like the Discomfort Intolerance Scale (DIS; [17]) and physical stress tests linked to specific mental health conditions such as PTSD [18], as well as symptoms of anxiety and depression (Bernstein et al. 2011). Interestingly only the DTS showed correlations with disease severity, comorbidities, and overall quality of life in both these research studies [10].
The 4-item DTS-SF
Although the original 15-item DTS is a psychometrically solid tool for evaluating distress tolerance, there was a need for a shorter assessment tool, particularly in clinical settings as longer scales can lead to lower response quality [19]. To tackle this issue Garner and colleagues developed the DTS-SF [15]. They selected the highest loading items from each of the original DTS’s four subscales. The validity of the DTS SF was tested on individuals with obsessive-compulsive disorder (OCD) receiving inpatient treatment [15]. Furthermore, a subsequent study validated the DTS-SF in a sample of individuals with depressive symptoms, confirming its applicability across different clinical populations [20]. The DTS-SF demonstrated substantial associations with relevant measures and outcomes, demonstrating that lower DT was associated with increased symptom severity and worse quality of life. The DTS-SF also showed sensitivity to treatment effects, as participants scores notably improved during treatment sessions [15]. These results suggest that the DTS-SF is a valuable measure of distress tolerance.
The present study
This study intends to close the current gap by validating both the DTS and DTS-SF in a new language, nation, and non-Western Arabic-speaking cultural environment, which has not previously been explored, to better understand how this instrument operates in different cultural situations. Adults in the Arab world encounter several obstacles, including mental health issues, poor dietary habits, substance use and increasing exposure to violence, exacerbated by sociopolitical upheaval [21, 22]. Given these barriers, reliably assessing Distress Tolerance is critical not just for evaluating non-western adult’s mental health but also for implementing effective treatments. In this context, our study aims to examine the psychometric properties of an Arabic translation of the DTS and DTS-SF, expanding its usefulness and contributing to a better global understanding of distress tolerance in the Arab region. By accomplishing this, we hope to illuminate our understanding of how cultural differences impact the way Arabic-speaking adults endure and tolerate distress. It is expected that the Arabic translation of the DTS and DTS-SF will show good reliability and validity in a sample of Arabic speaking adults, demonstrating its strength and relevance across diverse cultural contexts.
