Background:Physical activity (PA) is essential for health, but many adults find PA adherence challenging. Acceptance of discomfort related to PA may influence an individual’s ability to begin and sustain a program of exercise. The aim of this study was to evaluate the psychometric properties of the Physical Activity Acceptance Questionnaire (PAAQ).Methods:The PAAQ was administered to 3 distinct samples (N = 418). Each sample completed additional self-report measures; 1 sample also wore accelerometers for 7 days (at baseline and 6 months later).Results:The PAAQ demonstrated high internal validity for its total score (α = .89) and 2 subscales (Cognitive Acceptance α = .86, Behavioral Commitment α = .85). The PAAQ also showed convergent validity with measures of mindfulness, self-reported physical activity levels, and accelerometer-verified levels of moderate-to-vigorous PA (MVPA; P-values < .05). The Cognitive Acceptance subscale showed predictive validity for objectively-verified PA levels among individuals attempting to increase PA over 6 months (P = .05). Test-retest reliability for a subset of participants (n = 46) demonstrated high consistency over 1 week (P < .0001).Conclusions:The PAAQ demonstrates sound psychometric properties, and shows promise for improving the current understanding of PA facilitators and barriers among adults.

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.

Abstract Background Research on the psychometric properties of the Persian self-report form of the Pediatric Quality of Life Inventory Version 4.0 (PedsQL 4.0) in adolescents has several gaps (e.g., convergent validity) that limit its clinical application and therefore the cross-cultural impact of this measure. This study aimed at investigating the psychometric properties of the PedsQL 4.0 and the effects of gender and age on quality of life in Iranian adolescents. Method The PedsQL 4.0 was administered to 326 adolescents (12–17 years). A subsample of 115 adolescents completed the scale two weeks after the first assessment. Confirmatory Factor Analysis (CFA), correlation of the PedsQL 4.0 with the Weiss Functional Impairment Rating Scale-Self-report (WFIRS-S), and Item Response Theory (IRT) analysis were conducted to examine validity. Cronbach’s alpha, McDonald’s Omega, and Intra class correlation (ICC) were calculated as well to examine reliability. Gender and age effects were also evaluated. Results Internal consistency and test–retest reliability of the total PedsQL 4.0 scale was .92 and .87, respectively. The PedsQL 4.0 scores showed negative moderate to strong correlations with the WFIRS-S total scale. The four-factor model of the PedsQL 4.0 was not fully supported by the CFA—the root mean square error of approximation and the comparative fit index showed a mediocre and poor fit, respectively. IRT analysis indicated that all items of the PedsQL 4.0 fit with the scale and most of them showed good discrimination. The items and total scale provided more information in the lower levels of the latent trait. Males showed significantly higher scores than females in physical and emotional functioning, psychosocial health, and total scale. Adolescents with lower ages showed better quality of life than those with higher ages in all scores of the PedsQL 4.0. Conclusion The PedsQL 4.0 showed good psychometric properties with regard to internal consistency, test–retest reliability, and convergent validity in Iranian adolescents, which supports its use in clinical settings among Persian-speaking adolescents. However, factor structure according to our CFA indicates that future work should address how to improve fit. In addition, studies that include PedsQL 4.0 should consider gender and age effects were reported.

Background:The Multimedia Activity Recall for Children and Adults (MARCA) is a computerized recall instrument that records use of time during 24 hr the previous day and has been developed to address limitations of current self-report physical activity measures for those in advanced age.Methods:Test–retest reliability and convergent validity of the adult MARCA were assessed in a sample of 45 advanced-age adults (age 84.9SD ±1.62 yr) as a subsample of the Life and Living in Advanced-Age Cohort Study New Zealand (LiLACS NZ). Test–retest methods required participants to recall the previous day’s activity using the MARCA twice within the same day. Convergent validity was assessed against accelerometry.Results:Test–retest reliability was high, with ICCs greater than .99 for moderate to vigorous physical activity (MVPA) and physical activity level (PAL). Compared with accelerometry, the MARCA demonstrated validity comparable to other self-report instruments with Spearman’s coefficients of .34 and .59 for time spent in nonsedentary physical activity and PAL.Conclusion:The MARCA is a valid and reliable self-report tool for physical activity behaviors in advanced-age adults.

Background:The International Physical Activity Questionnaire (IPAQ) has received significant attention since the late 1990s. As it currently stands, its long version has been translated in English, German, Icelandic, Korean, Polish, Spanish, Turkish, and Vietnamese. However no data originating from the self-administered long version (last 7 days) of the IPAQ (IPAQ-SALV) is available for French Canadians. This study developed a self-administered long version (last 7 days) of the IPAQ in Canadian French (IPAQ-SALVCF) and assessed its psychometric properties.Methods:The original IPAQ-SALV was linguistically translated, back-translated, and then reviewed in a focus group to ensure its meaning had been retained. Data were collected on a sample of 34 Francophones from Northern Ontario, and the results compared with step counts assessed by 7-day pedometer recording. Test-retest reliability was examined with a 24-hour delay between questionnaire completion on day 8 and day 9 of the protocol. Convergent validity was assessed by comparing IPAQ-SALVCF (last 7 days) results to average step counts over a 7-day period.Results:Intra-class correlation coefficients (ICC) revealed that the IPAQ-SALVCF results were stable between days. The ICC for total activity scores was highest at 0.93 (CI: 0.86 to 0.97). Total activity scores were also significantly related to pedometer step counts (Pearson r = .66 P < .01). These results confirm those obtained in prior researchConclusion:The IPAQ-SALVCF is a reliable and valid measure of physical activity for French Canadians.

Described are the development and initial psychometric properties (Ns = 50 and 188) of a self-report measure, the Student Worry Questionnaire–30, for use with college undergraduates Exploratory principal components analyses (Ns = 388, 350, and 396) with oblimin rotation indicated six domains of worrisome thinking, financial-related concerns, significant others' well-being, social adequacy concerns, academic concerns, and general anxiety symptoms. The total score and scale scores showed internal consistency of .80 to .94. Also, test-retest reliability analyses (.75 to .80) support consistency of responses over 4 wk. Strong evidence for convergent validity was indicated. Confirmatory factor analysis confirmed the fit of the 6-factor oblique model. Limitations of the present studies, and directions for research are discussed.

Test Retest Reliability

The psychometric properties of a new scale, the Obsessive Compulsive Inventory (OCI; Foa, Kozak, Salkovskis, Coles, & Amir, 1998), were examined in a nonclinical student sample. The study was a partial replication of the original validation study by Foa et al. Test-retest reliability, internal consistency, and convergent validity were examined using a sample of 126 undergraduate psychology students. Statistical analyses (Pearson's r and Cronbach's alpha) indicated adequate test-retest reliability for the full scales and subscales (coefficients ranging from 0.69 to 0.88) and high internal consistency (all coefficients exceeding 0.7). Convergent validity with the Maudsley Obsessional Compulsive Inventory (MOCI; Hodgson & Rachman, 1977) was adequate for the full scales and for the Washing and Checking subscales (coefficients ranging from 0.61 to 0.75). The OCI is a useful supplement to existing self-report measures of obsessive-compulsive symptomatology.

Objective: The Weiss Functional Impairment Rating Scale–Self-Report Form (WFIRS-S) was developed as a measure of functional impairment in adolescents and adults with ADHD. This study reports the psychometric properties of the Persian version of the WFIRS-S in a sample of normal Iranian adolescents. Method: Internal consistency and factor structure of the WFIRS-S were tested on a sample of 386 students (Grades 7-12). The test-retest reliability and the convergent validity of the WFIRS-S were evaluated by using two different subsamples including 50 and 100 students, respectively. Results: The Cronbach’s alpha values were between .72 and .94 for the WFIRS-S subdomains and total scale. The test-retest reliability was .80 for the total scale. The WFIRS-S subdomains had moderate to high significant correlations with the Pediatric Quality of Life total scale. Conclusion: The Persian version of the WFIRS-S has acceptable psychometric properties and could be used as a functional impairment assessment for adolescents.

Abstract Objective Insomnia is a highly prevalent sleep disorder that is particularly common among adolescents with health conditions. We aimed to develop and validate a brief screening measure of insomnia in adolescents that can be used across clinical and community samples. We hypothesized that we would identify evidence supporting reliability, convergent/discriminant validity, and that we would determine preliminary clinical cutoff scores. Methods A team of experts in behavioral sleep medicine developed a 13-item brief screening measure of insomnia in adolescents (Adolescent Insomnia Questionnaire [AIQ]). We evaluated the psychometric properties of the AIQ in a sample of 315 youth (11–18 years old, Mean = 14.90, SD = 2.02; 64% female) who had chronic pain (n = 37), headache (n = 170), insomnia diagnosed by a sleep specialist (n = 22), or were otherwise healthy (n = 86). Results Using Exploratory and Confirmatory Factor Analysis, we identified three subscales consistent with major diagnostic criteria of insomnia. As expected, the measure showed strong reliability through high internal consistency (α =.91). We also found strong convergent validity through expected positive relationships between the AIQ and self-report measures of sleep disturbance, and divergent validity via weak relationships with parent-report of snoring. Results of receiver operating characteristic (ROC) identified a clinical cutoff score that may assist in clinical decision making. Conclusions We found that the AIQ has sound psychometric properties in a large heterogeneous sample of treatment-seeking youth and youth from the community. The AIQ can quickly screen adolescent insomnia and could address an important clinical need in identifying youth in need of insomnia treatment in pediatric practice settings.

Objective: To develop a self-report scale of subjective experiences of illness perceived to impact on employment functioning, as an alternative to a diagnostic perspective, for anticipating the vocational assistance needs of people with schizophrenia or schizoaffective disorders. Method: A repeated measures pilot study (n1 = 26, n2 = 21) of community residents with schizophrenia identified a set of work-related subjective experiences perceived to impact on employment functioning. Items with the best psychometric properties were applied in a 12 month longitudinal survey of urban residents with schizophrenia or schizoaffective disorder (n1 = 104; n2 = 94; n3 = 94). Results: Construct validity, factor structure, responsiveness, internal consistency, stability, and criterion validity investigations produced favourable results. Work-related subjective experiences provide information about the intersection of the person, the disorder, and expectations of employment functioning, which suggest new opportunities for vocational professionals to explore and discuss individual assistance needs. Conclusion: Further psychometric investigations of test-retest reliability, discriminant and predictive validity, and research applications in supported employment and vocational rehabilitation, are recommended. Subject to adequate psychometric properties, the new measure promises to facilitate exploring: individuals' specific subjective experiences; how each is perceived to contribute to employment restrictions; and the corresponding implications for specialized treatment, vocational interventions and workplace accommodations.

This study evaluated the psychometric properties of a Chinese version of the 24-item Social Environment Questionnaire (SEQ-C). Confirmatory factor analysis was used to examine the factor validity and measurement invariance (Purpose 1) of the SEQ-C in 453 older adults in Hong Kong. Convergent validity (Purpose 2) and test–retest reliability (Purpose 3) were also measured. The results of the confirmatory factor analysis and measurement invariance supported the four-factor structure (representing companionship, encouragement, neighborhood social cohesion, and role models) of the SEQ-C, in a 15-item model that closely fitted the data. The SEQ-C was also found to have acceptable to satisfactory internal consistency, test–retest reliability, composite reliability, and moderate convergent validity in correlating perceived social support. This study showed that the SEQ-C is a suitable means of measuring the social environments of older adults in Hong Kong.
