Psychometric Properties of an Iranian Version of the Response to Stressful Experiences Scale (RSES)

Abstract Objective: Few psychometric scales have been developed to measure resilience and related constructs such as Response to Stressful Experiences in military. This study aimed to translate and validate the Response to Stressful Experiences Scale (RSES), a measure of individual differences in cognitive, emotional, and behavioral responses to stressful life events in Iranian Military Personnel. Method: In this methodological study, 501 Military personnel were selected by convenience sampling from three military units in Tehran, Iran .The forward backward-procedure was applied to translate the questionnaire from English into Persian. Face validity, Content validity, construct validity (EFA, CFA) and convergent validity have been employed to validate the prepared scale. Cronbach’s alpha coefficients and the test-retest were used to assess the scale reliability. Results: By performing EFA on the first sample part (n = 300), the exploratory factor analysis showed that the present scale has three factors. The factors were called as active coping, meaning-making and flexibility, resiliency, according to their content and the research, which explained 37.5% of the overall extracted variance. CFA was performed on the second part of the sample (n = 201), to test the fitness of the 3-factor solution. The confirmatory factory analysis showed a moderate fit for the data (CFI = 0.930, CMIN/DF = 1.879, RMSEA =0.060). The 3-factors subscales were associated with the Connor– Davidson Resilience Scale (CD-RISC), indicating the good convergent validity of RSES. The internal consistency was acceptable (active coping=.0.761, meaning-making and flexibility=0.863, resiliency=0.865 and Cronbach's alpha of the total was 0.920). The ICC value of 0.91 ranging from 0.79 to 0.87 was found for the whole scale and the subscales. Conclusion: The findings suggest that the Persian version of the RSES has acceptable psychometric properties. Therefore, it can be used to measure Response to Stressful Experiences or resiliency in research and clinical settings.

Background: No standard self-report instrument for withdrawal symptoms is available in Iran. Objectives: This study aimed to evaluate the psychometric properties of the Persian version of the 10-item Amphetamine Withdrawal questionnaire version 2 (AWQV2). Methods: A sample of 388 methamphetamine addicts (215 females and 173 males) referred to addiction recovery centers and psychiatric ward of Farabi Hospital in Kermanshah. A two-stage random sampling method was used. The reliability and internal consistency of the AWQV2 items were examined using Cronbach’s alpha and test-retest reliability, respectively, and the instrument validity of the AWQV2 was measured using construct validity and convergent validity. Results: The AWQV2 had a Cronbach’s alpha of 0.72. Factor analysis using the main component analysis with a varimax rotation introduced three factors of hyperarousal, anxiety, and reversed vegetative symptoms. These factors explained 0.58 of the total variance. The coefficient of test-retest reliability at a 2-week interval was equal to 0.77. The convergent validity of the AWQV2 was examined by simultaneously administering the Advanced Warning of Relapse (AWARE) questionnaire to 40 subjects, with a correlation coefficient of 0.81. Conclusions: Based on the results, the AWQV2 has very good psychometric properties and may be used in research and therapeutic interventions.

IntroductionThe adult hope scale (AHS) was developed as measure of hope with a 12-item using an 8-point Likert-type scale (Snyder et al., 1991). Although there is an Arabic version of AHS, it is not identical to the original version in terms of the number of items response.ObjectivesTo evaluate the psychometric properties of the Arabic version of the AHS in undergraduate sample.MethodsThe participants were undergraduate Kuwaitis (1000) males and (1000) females. The mean age of the males was (20.25 ± 0.05) years, and for females was (19.96 ± 1.44) with a significant age difference (t = 4.22. P < .000). The Arabic version of the AHS was administered to participants. The internal consistency reliability, factor structure, and convergent validity of the AHS with Life Orientation Test (LOT-R), oxford happiness inventory (OHI), and Satisfaction With Life Scale (SWLS),while the divergent validity of AHS were assessed with Beck Depression Inventory-II (BDI-II) and the beck anxiety inventory (BAI).ResultsInternal consistency was satisfactory for the AHS (Cronbach's alpha = 0.83) for males and (Cronbach's alpha = 0.81) for females. The results revealed no significant gender differences on happiness (F = 1.68, P > .05). Principal component analyses (PCA) showed that a three -component solution explains %54.56 of the total variance for males and 51.99% for females. The AHS positively correlates with the following variables: SWLS (r = .43), LOT-R (r = 0.40) OHI (r = .49) while the AHS correlates negatively with BDI-II (r = −.49) and with BAI (r = −.39).ConclusionsThis study provides evidence for the reliability and validity of the Arabic AHS for Kuwaitis.Disclosure of interestThe author has not supplied his/her declaration of competing interest.

Eyberg Child Behavior Inventory

Objective: Eyberg Child Behavior Inventory (ECBI) is one of the most frequently used tools for measuring behavioral problems; however, no research has been done to evaluate its psychometric properties in Iran. Method: The present study sought for exploring the factor structure and psychometric properties of the F-ECBI in an Iranian sample. A total of 495 mothers (mean age = 33.83 years; SD = 4.78) who reported behavioral problems in their children aged 3 to 12 years (mean age = 6.36 years; SD = 2.66) were selected via convenience sampling in 2018-2019. The psychometric properties of F-ECBI, including reliability (Cronbach’s alpha) and validity (exploratory and confirmatory factor analysis, and convergent validity) were assessed using SPSS version 25 and LISREL 8.80. Results: By performing EFA on the first sample part (n = 360), the examination of scree plot supported a 3-factor or 4-factor solution, and pattern matrix resulted in a 3-factor structure. The factors were called as “behavioral problems related to oppositional defiant”, “behavioral problems related to inattentive”, and “behavioral problems related to conduct”, according to their content and the research. CFA was performed on the second part of the sample (n = 135) to test the fitness of the 3-factor solution. According to CFI (0.91), NFI (0.91), NNFI (0.90), IFI (0.91), PNFI (0.77), GFI (0.75) AGFI (0.70), PGFI (0.62) and chi-square (540.31) indexes, the model had acceptable fitness. Cronbach's alpha was employed to measure the internal consistency and it revealed to be at a good to excellent level (behavioral problems related to oppositional defiant = 0.88; behavioral problems related to inattentive = 0.84; behavioral problems related to conduct = 0.74). The 3-factors subscales were associated with total difficulties, internalizing and externalizing SDQ, indicating the good convergent validity of F-ECBI. Conclusion: The F-ECBI has good psychometric properties in Iran and can be employed as a useful instrument for measuring children's behavioral problems.

AIMS: This study aimed to translate the psychosocial impact of dental esthetics questionnaire (PIDAQ) to Farsi and assess its cultural adaptation, validity, and reproducibility. MATERIALS AND METHODS: The PIDAQ was translated to Farsi by experts fluent in Farsi and English. It was then back-translated to English by another expert blinded to the original version. The translated version was administered among 40 patients to assess its face validity and content validity. Final version of the questionnaire along with the index of orthodontic treatment need (IOTN) and the perception of occlusion scale (POS) was administered among 400 patients (224 females, 176 males) to assess their need for orthodontic treatment. To assess its validity, the mean score of PIDAQ was evaluated in different ranges of IOTN-esthetic component (IOTN-AC), IOTN-dental health component (DHC), and POS. To assess its convergent validity, the PIDAQ, IOTN-AC, IOTN-DHC, and POS scores were evaluated. Its construct validity was evaluated by confirmatory and exploratory factor analysis. Its internal consistency was evaluated using Cronbach’s alpha and the split-half method. Its test-retest reliability was evaluated by calculating the intraclass correlation coefficient (ICC). RESULTS: The Cronbach’s alpha was found to be 0.900–0.945 for the questionnaire domains, which showed good reliability. The ICC for the four questionnaire domains was 0.926, which was excellent. IOTN-DHC, IOTN-AC, and POS had significant correlations with the questionnaire domains. CONCLUSIONS: The Farsi version of PIDAQ has optimal validity and reliability and can be used for assessment of the dental esthetics-related quality of life of Iranian young adults.

Abstract Background The aim of the present study was to evaluate the psychometric properties of the Persian version of delivery fear scale (DFS) among Iranian women population. Methods This is a methodological study that was conducted to evaluate the psychometric properties of DFS. Convenience sampling was used to select 200 pregnant women from the maternity ward of Razi Hospital in Ahvaz, Iran. In the first step, the scale was translated into Persian using backward-forward translation method. Afterwards, the following types of validity were examined: face validity based on impact score, construct validity based on confirmatory factor analysis (CFA), and concurrent validity. The Pearson correlation test was used to determine the correlation of DFS with pregnancy-related anxiety questionnaire (PRAQ), Childbirth Attitude Questionnaire (CAQ), Spielberger’s state-trait anxiety inventory (STAI), and the short form of Lowe’s childbirth self-efficacy inventory. Reliability of DFS was assessed by determining internal consistency (Cronbach’s alpha) and split-half method. Results CFA had satisfactory validity considering x2⁄df < 5 and the RMSEA < 0.08. /the obtained Cronbach’s alpha coefficient was 0.77. The split-half coefficient of the questionnaire was 0.83, indicating an acceptable reliability for the questionnaire. The results showed that DFS had a direct significant correlation with the CAQ (r = 0.72), PRAQ (r = 0.74), STAI-Y1 (r = 0.71) and STAI-Y1 (r = 0.63) and a reverse significant correlation with subscales of the short form of Lowe’s childbirth self-efficacy inventory including outcome expectancy (r= -0.75) and self-efficacy expectancy (r= -0.76). Conclusions The findings of the present study confirm the validity and reliability of the Persian version of DFS as an instrument for measuring fear of childbirth (FOC) in Iranian women population.

Abstract Background: Internet addiction is a serious problem that can negatively impact both the physical and mental health of individuals. The Internet Addiction Test (IAT) is the most common and worldwide used instrument to screen internet addiction. This study sought to investigate the psychometric properties of an Indonesian version of the IAT.Methods: A total of 643 high school students participated in the study. The IAT questionnaire was made the focus of forward translation, expert panel discussions, back translation, a face validity study, a pilot study, and a psychometric properties evaluation. Factor structure was analysed by exploratory (EFA) and confirmatory factor (CFA) analyses, whereas reliability was measured with Cronbach’s alpha coefficient.Results: The factor analysis revealed that a three-factor model of the Indonesian version of the IAT identified in the EFA displays better psychometric properties than a one-factor model of the same. The Cronbach’s alpha score is 0.855. A significant association was also observed between the level of internet addiction with gender (p = 0.027) and the duration of internet use per day (p = 0.001).Conclusion: The Indonesian version of the IAT provides good validity and reliability in a three-dimensional model. Therefore, it can be utilised as a tool for screening internet addiction in the Indonesian population.

ObjectivesThere is growing evidence that patients can provide feedback on the safety of their care. The 44-item Patient Measure of Safety (PMOS) was developed for this purpose. While valid and reliable, the length of this questionnaire makes it potentially challenging for routine use. Our study aimed to produce revised, shortened versions of PMOS (PMOS-30 and PMOS-10), which retained the psychometric properties of the longer version.ParticipantsTo produce a shortened diagnostic measure, we analysed data from 2002 patients who completed PMOS-44, and examined the reliability of the revised measure (PMOS-30) in a sample of 751 patients. To produce a brief standalone measure, we again analysed data from 2002 patients who completed PMOS-44, and tested the reliability and validity of the brief standalone measure (PMOS-10) in a sample of 165 patients.MethodsThe process of shortening the questionnaire involved a combination of secondary data analysis (eg, Standard Deviation and inter-item correlations) and a consensus group exercise to produce PMOS-30 and examine face validity. Analysis of PMOS-30 data examined reliability (eg, Cronbach’s alpha). Further secondary data analysis (ie, corrected item-total correlations) produced PMOS-10, and primary data collection assessed its reliability and validity (eg, Cronbach’s alpha, analysis of variance).ResultsFourteen items were removed to produce PMOS-30 and the percentage of negatively worded items was reduced from 57% to 33%. PMOS-30 demonstrated good internal reliability (α=0.89). The 10 items with the highest corrected item-total correlations across both PMOS-44 and PMOS-30 composed PMOS-10. PMOS-10 had good internal reliability (α=0.79), demonstrated convergent validity; however, discriminant validity was not established.ConclusionsTwo revised, shortened versions of the original PMOS-44 (PMOS-30 and PMOS-10) were produced to capture patient feedback about safety in hospital. The measures demonstrated good reliability and validity, and preserved the psychometric properties of the original measure.

Abstract Introduction: Cancer of the cervix has a progressive character and is one of the most significant public health problems in many countries. Our research aimed to translate EORTC QLQ CX 24 (European Organization for Research and Treatment of Cancer; Quality of life questionnaire-cervical cancer 24) from English to Serbian, to create essential cultural adaptations and to analyze psychometric properties of the translation in a model of female inpatients with cancer of the cervix. Method: The QLQ CX 24 was translated and adapted according to internationally established guidelines, and then tested on a sample of 100 Serbian females with cancer of the cervix. The testing was repeated three times on the same patients. We calculated the internal consistency (Cronbach’s alpha), criterion validity, convergent validity, and discriminative validity of the QLQ CX 24. We used factor analysis to discover the original construct. Results: The Serbian translation of QLQ CX 24 showed good internal consistency, showed satisfactory reliability, and temporal stability. In the first, when was rated by the investigators Cronbach’s alpha was 0.607, and one month later when the questionnaire also was rated by investigators Cronbach’s alpha was 0.696. When the scale was rated by females themselves Cronbach’s alpha was 0.802. Divergent as well as convergent validity tests had good results. The factorial analysis exposed six domains.Conclusion: The Serbian translation of QLQ CX 24 is a trustworthy and appropriate specific instrument for measuring the quality of life in females with cervical cancer.

Background and Aims: Mentalized affectivity is a new approach that expresses the process of emotion regulation through a dynamic perspective. Since social-cognitive variables and cultural context play a major role in the process of mentalized affectivity, the present study aimed to assess the psychometric properties of the Mentalized Affectivity Scale in Iran. Materials and Methods: A total of 447 students were selected via the convenience sampling method. The Persian version of Mentalized Affectivity Scale was administered simultaneously with other scales. exploratory and confirmatory factor analyses was used to evaluate the validity of the scale. Moreover, convergent validity and divergent validity of this scale were assessed with other scales. The reliability of the scale was calculated by Cronbach's alpha, coefficient theta, and composite reliability. Results: The results of exploratory factor analysis showed four factors of emotion recognition, emotion processing, emotion tracing, and emotion expression. The significant correlation of factors with the used scales pointed to the content validity and divergent validity of the scale. Cronbach's alpha coefficient for the entire scale was 0.93. The composite reliability of the factors was in the range of 0.82-0.89, and the coefficient theta of the scale was reported as 0.98. With respect to average variance extracted (AVE) greater than 0.5 and composite reliability greater than 0.8, the convergent validity of the factors was confirmed. Conclusion: As evidenced by the obtained results, the Persian version of the Mentalized Affectivity Scale is a valid scale in the field of emotion regulation and social cognition that can be used for Iranian populations. The factor structure includes four factors.
