This article describes the psychometric evaluation of the Modified Reminiscence Functions Scale (MRFS). The 39-item MRFS was validated on a sample of 271 racially diverse older adults. Psychometric analysis included content validity, item analysis, principal component analysis with varimax rotation, test–retest reliability, and internal consistency reliability using Cronbach’s alpha. The model’s structure supports a seven-factor, 39-item scale. Test–retest and Cronbach’s alpha for the instrument were .82 and .94, respectively. The seven-factor scale: self-regard, death, bitterness, intimacy, teach–inform, boredom, and conversation accounted for 61% of variance. Evidence indicates the self-report Likert instrument is a reliable and valid measure of reminiscence functions. Cross-validation with other populations and further research is needed to identify other reminiscence dimensions–functions.

Interruptions caused by frequent smartphone use steals attention away from daily activities, bringing serious implications onto an individual’s health, safety and education. Smartphone Use Questionnaire (SUQ) is a 20-item questionnaire developed to assess the pattern of smartphone use and its effect on attention. This study was done to translate and validate the Malay-language version of the SUQ and to measure the psychometric properties of the Malay-version SUQ to justify its use in Malaysia. A forward and back-translation was done by four individuals, who were three physicians and one linguist. Content and face validity was done involving three experts who were a linguist, psychiatrist and epidemiologist. Psychometric testing was conducted on a sample of 195 individuals proficient in the Malay language. A construct validity test was performed using factor analysis and the internal reliability was tested by calculating for the Cronbach’s Alpha. The age range of the sample was 13-59 years, most of which were female and of the Malay race. Using principal component analysis with direct oblimin rotation, the factor analysis extracted two components similar to the original study: General Use and Absent-Minded Use. However, question number 20 was grouped into General Use component, whereas in the original study it was under the Absent- Minded Use component. The Cronbach’s Alpha for the obtained components was 0.884 and 0.927, respectively. This study found that the Malay-version SUQ was a valid and reliable instrument for use in Malaysia in assessing inattention associated with smartphone use.

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.

Introduction: Since the development of the 10 item Purdue Pharmacist Directive Guidance (PPDG) Scale several studies of the psychometric properties of the PPDG have been conducted. Although Cronbach's alpha was calculated as a means of internal consistency reliability, a demonstration of the mean centering of the individual items from the instrument were not explored. Objectives: This study focused on investigating the mean stabilization of items within the PPDG as they pertain to Cronbach's reliability coefficient calculation. Methods: Using item analysis procedures in SPSS, the mean stability of items within the general factor of directive guidance and subscales of instruction and feedback and goal setting were examined for the PPDG. Results: Mean stability scores for entire PPDG scale and the subscales of instruction and feedback and goal setting were strong. Also, corrected item-total correlations and Cronbach's alphas following item deletion were good for the overall PPDG scale and the subscales. Conclusions: The results provide evidence to enhance understanding of the psychometric stability of the PPDG scale and its subscales.   Type: Original Research

Background: The objective of this study was to investigate the psychometric properties of the Threadgold Communication Tool (TCT). Method: Internal consistency reliability was measured using Cronbach's α coefficient and inter-item correlation. Test-retest was performed to examine the instrument's stability. Exploratory principal component analysis (PCA) with oblimin rotation was carried out to evaluate construct validity. Finally, the score on each item of the TCT was correlated with the person's Mini Mental State Examination (MMSE) and Barthel Index of activities of daily living scores. Results: A total of 51 persons participated, with a mean age of 86.7 (SD 6.6) years, of whom 46 were women with moderate-to-severe dementia [mean MMSE score 7.5 (SD 6.7)]. There were two measurement points 2 weeks apart. The results showed a satisfactory level for internal consistency and a high test-retest reliability (r = 0.76). The corrected item-total correlation ranged between 0.50 and 0.87, and a two-factor structure was revealed at the PCA. ‘Vocalizing' seemed to measure another aspect of communication and was the only item which was negatively loaded. Conclusion: Despite the low sample size in this study, the results revealed the TCT as a reliable and valid instrument, suitable for measuring communication among people with dementia. We suggest clarifying the understanding of ‘vocalizing' before considering removing it from the scale.

Background and Purpose: This article tests the construct validity of the Attitudes to Disability Scale (ADS) for use with nurse educators. The ADS was designed to assess the attitudes of people with disabilities and the general population. Methods: The responses of 126 nurse educators were analyzed using multivariate statistics. Results: Reliability analysis of the original ADS factors yielded Cronbach’s alpha of .655, .689, .781, and .621 (Inclusion, Discrimination, Gains, and Prospects, respectively). Principal component analysis confirmed factors Discrimination and Gains and identified two new factors. Principal axis factor confirmed Discrimination and Gains and defined one new factor (Opportunity) with a Cronbach’s alpha of .73. Conclusions: The original form ADS is not reliable for use with nurse educators although a modified version may prove suitable.

Schema Questionnaire

La existencia de esquemas maladaptativos tempranos (EMTs) es el concepto central de Schema Therapy (ST). Varios estudios han demostrado que los EMS están involucrados en muchos trastornos psiquiátricos. El Young Schema Questionnaire es una medida de autoinforme desarrollada para evaluar los 18 EMTs y tiene versiones de forma larga (YSQ-L) y forma corta (YSQ-S). Actualmente se encuentra en su tercera versión (YSQ-S3). Hasta donde tenemos conocimiento, este es el primer estudio que tiene como objetivo validar el YSQ-S3 de acuerdo con la nueva organización propuesta de EMTs en cuatro dominios. Una muestra no clínica de 1372 estudiantes italianos participó en esta investigación. El análisis factorial confirmatorio (CFA) se realizó para examinar la estructura latente del YSQ-S3, incluidas las estructuras de primer y segundo orden. Se calcularon los coeficientes de correlación alfa e intraclase de Cronbach para evaluar la consistencia interna y la fiabilidad test-retest. Las correlaciones entre el YSQ-S3 y la ansiedad y los síntomas del estado de ánimo se calcularon para medir la validez de constructo. El alfa de Cronbach de casi todos los EMTs fue superior a 0.7, lo que indicó una buena confiabilidad interna, y la confiabilidad test-retest fue excelente. CFA apoya la nueva organización propuesta de EMS en cuatro dominios. Con respecto a la validez concurrente, cada esquema en el YSQ-S3 estaba altamente correlacionado con la ansiedad y los síntomas del estado de ánimo. El nuevo modelo de cuatro dominios del YSQ-S3 ha demostrado que puede ser una herramienta útil y válida para los médicos e investigadores en la medición del autoinforme de los EMTs. The existence of early maladaptive schemas (EMS) is the core concept of Schema Therapy (ST). Several studies have demonstrated that EMSs are involved in many psychiatric disorders. The Young Schema Questionnaire is a self-report measure developed to assess the 18 EMSs and has long form (YSQ-L) and short form (YSQ-S) versions. It is currently in its third version (YSQ-S3). To the best of our knowledge, this is the first study that aims to validate the YSQ-S3 according to the new proposed organization of EMSs into four domains. A non clinical sample of 1372 Italian population was involved in this research. Confirmatory Factor Analysis (CFA) was conducted to examine the latent structure of the YSQ-S3, including both first- and second-order structures. Cronbach’s alpha and intra-class correlation coefficients were calculated to evaluate internal consistency and test-retest reliability. Correlations between the YSQ-S3 and anxiety and mood symptoms were calculated to measure construct validity. Cronbach’s alpha of almost all EMSs were higher than 0.7, which indicated good internal reliability, and test-retest reliability was excellent. CFA supports the new proposed organization of EMSs into four domains. Regarding concurrent validity, each schema in the YSQ-S3 was highly correlated with anxiety and mood symptoms. The new four-domains model of the YSQ-S3 has demonstrated that it can be a useful and valid tool for clinicians and researchers in the self-report measurement of EMSs.

Background: Amyotrophic Lateral Sclerosis-Specific Quality of Life-Revised (ALSSQOL-R) encompasses 50 items which assess quality of life (QOL) in patients with amyotrophic lateral sclerosis (ALS) in six major domains. This study aims to translate the ALSSQOL-R into Persian and evaluate its reliability and validity among Iranian patients. Methods: ALSSQOL-R was translated by the standard multi-step forward-backward method. Content validity was calculated using item content validity index (I-CVI). Three items in the “intimacy” domain were deleted considering Iranian culture. Cronbach’s alpha was used for all 6 dimensions to calculate the internal consistency reliability. Test-retest reliability was evaluated using intraclass correlation coefficient (ICC) with one-month interval. Concurrent validity was measured by the validated version of 36-Item Short Form Health Survey (SF-36) questionnaire. Results: Sixty-three patients with ALS were enrolled in the study. I-CVI was 70%, promoted to 85% after modifications (acceptable). Regarding internal consistency reliability, Cronbach’s alpha in all six domains was  0.70 and total Cronbach’s alpha was 0.89 which is assumed as good. In terms of test-retest reliability, ICC [95% confidence interval (CI)] was 0.91 (91%) and Pearson correlation coefficient (r) was 0.90 (P < 0.001), all indicating an excellent reliability. The concurrent validity was established based on a strong correlation with SF-36 (r = 0.744, P < 0.001). Conclusion: The findings show that the modified

Early Trauma

AbstractIntroductionTraumatic experience in childhood or adolescence has a significant impact on the development of chronic mental and physical conditions in adulthood. Thus, it is very important for health professionals, especially primary care physicians to have an inventory in order to detect early trauma for planning appropriate treatment, such as the Early Trauma Inventory (ETI). The aim of this paper is to test the psychometric properties of the Slovenian translation of the short, self-rated version (ETISR-SF), and to further validate the instrument.MethodsThe research was done in two parts – qualitative and quantitative. In the qualitative part, a questionnaire was translated and culturally adapted using the Delphi method. For the quantitative part, 51 patients with substance use disorders hospitalized at the Centre for the Treatment of Drug Addictions were recruited, along with 133 controls. The psychometric properties of the questionnaire were checked. Internal consistency was calculated using Cronbach’s alpha, test-retest reliability was examined graphically using a Bland-Altman plot. Discriminant validity between groups was gauged using the independent samples t-test.ResultsConsensus in the Delphi study was reached in the second round. Cronbach’s alpha varied between 0.60 - 0.85. Of the four domains, physical abuse had the lowest Cronbach’s alpha. The test-retest reliability is high for all domains, with correlation coefficients ranging from 0.82 to 0.96. The non-clinical sample differed significantly from the clinical sample.ConclusionThe Slovenian translation of ETISR-SF is a satisfactory instrument for the evaluation of trauma before the age of 18.

Patient-centredness in care is a core healthcare value and an effective healthcare delivery design requiring specific nurse competences. The aim of this study was to assess (1) the reliability, validity, and sensitivity of the Finnish version of the Patient-centred Care Competency (PCC) scale and (2) Finnish nurses’ self-assessed level of patient-centred care competency. The PCC was translated to Finnish (PCC-Fin) before data collection and analyses: descriptive statistics; Cronbach’s alpha coefficients; item analysis; exploratory and confirmatory factor analyses; inter-scale correlational analysis; and sensitivity. Cronbach’s alpha coefficients were acceptable, high for the total scale, and satisfactory for the four sub-scales. Item analysis supported the internal homogeneity of the items-to-total and inter-items within the sub-scales. Explorative factor analysis suggested a three-factor solution, but the confirmatory factor analysis confirmed the four-factor structure (Tucker–Lewis index (TLI) 0.92, goodness-of-fit index (GFI) 0.99, root mean square error of approximation (RMSEA) 0.065, standardized root mean square residual (SRMR) 0.045) with 61.2% explained variance. Analysis of the secondary data detected no differences in nurses’ self-evaluations of contextual competence, so the inter-scale correlations were high. The PCC-Fin was found to be a reliable and valid instrument for the measurement of nurses’ patient-centred care competence. Rasch model analysis would provide some further information about the item level functioning within the instrument.
