The Effectivity of a School-Based Early Intervention Targeting Psychological Complaints and Non-Suicidal Self-Injury in Adolescents.

Background: Recent research suggests a concerning trend of non-suicidal self-injury (NSSI) and suicidal behaviors emerging at younger ages (as early as age 12). Early onset of NSSI is linked to more severe outcomes. While universal school-based prevention programs have shown promise in addressing suicidal behaviors, there is limited research on their effectiveness in preventing NSSI onset among adolescents. This study aims to evaluate the efficacy of a universal prevention program in schools for NSSI and mental complaints while enhancing resilience and mental health in 11-14-year-old adolescents. Methods: In total, 329 Flemish secondary school students (55.6% female), aged 11 to 14 years, participated in a 4 h classroom universal prevention, with a focus on emotion regulation, mental health, and specific strategies to prevent NSSI and reduce stigma. For both the intervention and control group (N = 124), a pre-, post-, and one-month follow-up questionnaire was administered, containing reliable and valid measures for NSSI and suicidality, emotion regulation, help-seeking behaviors, well-being, and psychological distress. Results: The prevention program effectively reduced NSSI and psychological distress, particularly for adolescents with a history of NSSI. Conclusions: These findings support previous research on the effectiveness of school-based programs in reducing mental complaints and suggest promising outcomes for NSSI prevention.

A Comparative Analysis of Emotional Regulation and Maladaptive Symptoms in Adolescents: Insights from Iran and Belgium.

(1) Background: Emotional regulation is a critical determinant of adaptive functioning during adolescence, exerting a profound influence on psychological well-being. This study seeks to deepen our understanding of the intricate interplay between emotional regulation and maladaptive psychological symptoms, examining these dynamics through a cross-country comparison. (2) Methods: A total of 224 adolescents, aged 13 to 21 years, from both Iran and Belgium, participated in a cross-sectional comparative study. The study aimed to elucidate the relationship between emotional regulation and mental health functioning, assessing internalizing symptoms, externalizing symptoms, and self-injury. A demographic questionnaire, the Emotion Regulation Inventory, the Strengths and Difficulties Questionnaire, and the Self-Harm Inventory, were administered. Data analysis incorporated correlation assessments, multivariate analysis of variance, and structured equation modeling. (3) Results: The findings revealed a positive association between emotional dysregulation and psychological symptoms across the entire sample. Conversely, emotional suppression, more prevalent in Iran, showed no significant link with maladaptive symptoms but was associated with self-harm in the Belgian sample. Cultural disparities were evident, with internalizing problems more prevalent in Iran and externalizing issues more common in Belgium. (4) Conclusions: Emotional dysregulation emerged as a common factor compromising mental health. It emphasizes the necessity of considering cultural nuances when developing interventional and preventative programs and calls for further research in this field.

Psychometric properties of the full-form and short-form versions of the Integration of Stressful Life Experiences Scale (ISLES) among Iranian university students.

BACKGROUND: Making adaptive meaning of stressful life experiences has been identified as an important determinant of adjustment. The Integration of Stressful Life Experiences Scale (ISLES) was developed to assess the outcome of meaning-making processes in the face of negative events. AIMS: The psychometric properties of this scale have not been measured in Iranian populations. The purpose of the present study was to examine the psychometric properties of the 16-item and 6-item versions of ISLES with a sample of 502 university students who had experienced relationship dissolution. RESULTS: Findings support a two-factor structure with acceptable validity and reliability. Positive correlations between the scores of ISLES with Centrality of Event Scale and PTSD symptoms provided evidence of concurrent validity. CONCLUSION: The results of measurement invariance indicated that both the 16-item and 6-item versions of ISLES are gender invariant and can be used to assess meaning-made in both men and women.

The Iranian form of psychometric properties of the Multidimensional Psychological Flexibility Inventory.

The Multidimensional Psychological Flexibility Inventory (MPFI) is a new 60-item self-report scale developed to assess the specific components of psychological flexibility and inflexibility proposed in the Hexaflex model of Acceptance and Commitment Therapy (ACT). The present study sought to examine the psychometric properties of the Persian version of the MPFI-60 in a community sample of 307 Iranian adults. The original study supported a 12-factor second-order structure consisting of 6 dimensions for psychological flexibility and 6 dimensions for psychological inflexibility. The Persian MPFI-60 demonstrated acceptable semantic and test content, internal structure, correlations with other variables, and internal consistency. It also evidenced in relation to anxiety, stress, depression, and self-compassion. Overall, the results indicate that the Persian MPFI-60 is a psychometrically sound measure in the Iranian context that enables researchers and clinicians to comprehensively assess the components of psychological flexibility and inflexibility within the Hexaflex model.

Intolerance of Uncertainty Scale-12: Psychometric Properties of This Construct Among Iranian Undergraduate Students.

Background: Uncertainty intolerance (IU), the tendency to think or react negatively toward uncertain events may have implication on individuals' mental health and psychological wellbeing. The Intolerance of Uncertainty Scale-12 (IU-12) is commonly used across the globe to measure IU, however, its' psychometric properties are yet to be evaluated in Iran with a Persian-speaking population. Therefore, the purpose of this research was to translate and validate the IU-12 among Iranian undergraduate students. Materials and Methods: The multi-stage cluster random sampling was employed to recruit 410 Iranian undergraduate students (260 females) from the Azad University to complete the IU-12, the Depression Anxiety Stress Scale-2, and the Penn State Worry Questionnaire in a cross-sectional design. In this study, face validity, content validity, construct validity, and concurrent validity were measured and Construct Reliability (CR) and Cronbach's alpha were used to measure reliability. Results: The impact score of the translated IU-12 indicated acceptable face validity (value of impact score was greater than 1.5). The value of Content Validity Index (CVI) and the value of Content Validity Ratio (CVR) were above 0.7 and 0.78, respectively. The values of CVI and CVR indicated the items had acceptable content validity and were deemed essential to the measure. The measurement model analysis showed the measure with two subscales had good fit indices (CMIN/df = 2.75, p < 0.01, RMSEA = 0.07, TLI = 0.94, CFI = 0.95, GFI = 0.94). A Confirmatory Factor Analysis (CFA) indicated the scale was composed of the two subscales found in the English-version of the scale (prospective anxiety and inhibitory anxiety), and no items were removed from the scale. The values of CR (0.86) and Cronbach's alphas (0.89) showed the measure had appropriate internal consistency. Conclusion: The findings support the psychometric properties of the Persian version of the IU-12. This scale could be used to reliably and accurately measure uncertainty intolerance among undergraduate students in Iran.

The Persian version of the centrality of event scale (CES): Assessment of validity and reliability among Iranian university students.

BACKGROUND: Event centrality, the extent to which an experience is perceived as a central event in one's life, has been found to be a strong correlate of posttraumatic stress disorder (PTSD). The centrality of event scale (CES) is commonly used in different conditions and cultures to measure trauma-related effects. However, the psychometric properties of this scale have not been investigated in the Iranian context. METHODS: The present study examined the psychometric properties of the Persian translation of the 7-item CES in a sample of 525 university students with a history of a romantic breakup. RESULTS: Confirmatory factor analysis confirmed a one-factor structure. The CES score was positively correlated with psychological inflexibility and PTSD symptoms. The measurement invariance analyses showed that the 7-item CES is gender invariant and can be used for both men and women. FINDINGS: Findings supported the good psychometric properties of the 7-item CES for measuring event centrality in Iranian university students.

Religious Perfectionism Scale: Assessment of Validity and Reliability Among Undergraduate Students in Iran.

Religious perfectionism is a construct that may help to either improve mental health or cause mental health difficulties. The Religious Perfectionism Scale (RPS; Wang in J Relig Health 59: 318-333, 2020) is a useful tool for assessing religious perfectionism around the world, but its psychometric properties have yet to be tested in Iran. The sample in the present study consisted of 300 Iranian undergraduate students (180 females) from Azad University who completed the RPS, the Depression Anxiety Stress Scale-2, and the Moral Perfectionism Scale. The impact score was used to determine face validity, and the values of the impact score for all translated items were greater than 1.5, meaning that the items had satisfactory face validity. The Content Validity Index (CVI) values were above the acceptable cutoff score of 0.7, indicating the acceptable content validity of items. The Content Validity Ratio (CVR) scores were greater than the cutoff score of the Lawshe table (.78), indicating the satisfactory essentiality of the items. To measure construct validity, the results of a confirmatory factor analysis (CFA) using AMOS software confirmed the scale with two subscales (zealous religious dedication and religious self-criticism). No item was removed from the scale as all factor loading values were greater than 0.49. The findings support the psychometric properties of the scale for measuring religious perfectionism among undergraduate students in Iran.
