Development And Validation

Background: The burden of migraine is determined by impairment during attacks due to pain or non-painful symptoms such as cognitive symptoms. Objective: Development of a questionnaire to measure self-reported subjective cognitive symptoms during migraine attacks. Methods: Item generation was accomplished through structured patient interviews analysed by a panel of experts. A set of 43 candidate items was applied to consecutive migraine patients. Test construction with factor analysis retained nine items. Internal consistency was assessed with Cronbach’s alpha and Spearman’s rho, and convergent and construct validity by correlation to spontaneous cognitive complaints, and the 43-item and the Cognitive Failures Questionnaires. Results: The nine-item Mig-SCog covers two domains, executive functions and language. Cronbach’s alpha was 0.82. It correlates with spontaneous cognitive complaints ( p < 0.001), the 43-item (rho = 0.69) and the Cognitive Failures Questionnaires (rho = 0.61). Test–retest reliability (Cohen’s kappa) was 0.55. Conclusions: Mig-SCog is a valid, reliable, consistent working instrument of fast self-administration that quantifies subjective cognitive symptoms during migraine attacks.

Abstract Background Coping strategies are essential in the cancer management/recovery process and show an integral part in patients with cancer globally. In Sri Lanka, validated scales to measure coping are scarce. This study was examined the Sinhalese version of the Brief COPE for its psychometric properties. Methods This scale is self-administered (28 items) and consists of adaptive and maladaptive coping strategies; divided into 14 subscales. Cancer patients were registered ‘first come - first serve’ basis using their appointment register at the Radiotherapy Unit, Oncology ward, Teaching Hospital, Karapitiya, Galle, Sri Lanka. They were requested to complete the Sinhalese version of the Brief COPE and demographic details. Test-retest reliability was checked using the same subjects two weeks later. Factorial validity was performed using exploratory factor and principal component analysis. Results were regarded as statistically significant if p < 0.05. Results The mean (±SD) age of the sample was 61(±12) years. The mean adaptive coping (±SD) and maladaptive coping were 37.50 (±8.14) and 17.10 (±2.44) respectively. The internal consistency of the overall scale was good (Cronbach’s alpha - 0.819). Adaptive and maladaptive coping showed a high Cronbach’s alpha (0.861 and 0.396). The test-retest reliability was found to be 0.66. The Sinhala version of BC was found to have a negative correlation with the CES-D scale but was positively correlated with the WHOQOL-BREF questionnaire. Seven factors were extracted. Conclusion The Sinhala version of the Brief COPE is a valid and reliable tool to assess coping strategies among patients with cancer. The findings of this study would let the health authorities get an understanding of coping strategies among patients with cancer; and the impact on cancer victims and family members to relieve their suffering.

A new construct, termed music receptivity, is introduced and discussed in this work. Music receptivity can be defined as a measure of the extent of internalization that an individual has, to a given piece of music, as measured at the point of listening. Through three studies, we demonstrate the psychometric properties of the construct—the Music Receptivity Scale (MRS). Exploratory factor analysis on a sample of 313 revealed good psychometric validity, with a four-factor solution (emotional experience, interest, attention, and hurdles), with a Cronbach’s alpha of 0.89, and a two-factor solution (emotion experience and attention), with a Cronbach’s alpha of 0.87. The tool also had a good test–retest reliability (r = 0.87 for a 15 day interval and r = 0.91 for 1 month interval). Overall, the tool had 20 items in the long form and 12 items in the short version. The MRS could distinguish musicians and non-musicians supporting its discriminant validity. We have also discussed the implication of the MRS in the field of music psychology.

This article focuses on the development of methods to measure personality and cognitive predisposition to monosemantic or polysemantic context generation (PCG).In accordance with the concept of V.S. Rotenberg, we assumed that PCG was connected with manual functional asymmetry. We developed four tests: one was designed to measure personality PCG, the other three measure cognitive PCG. Approbation samples consisted of 160—736 participants. Cronbach's alpha (0.67—0.93) and split-half coefficient (0.72—0.93) were calculated for all tests, for two of them test-retest reliability (0.47—0.91) was measured. Variance of personal PCG on 21.7% is explained by the variance of personality traits “reticence-sociability” and “concreteness-abstractness”. Personality and cognitive PCG are interconnected, but they have a fair amount of specificity. Manual functional asymmetry is weakly connected with personal PCG (not more than 1.5% of the common variance) and is not connected with cognitive PCG

Background: Curiosity is a personality characteristic, which fits with wellbeing and positive functioning. The objective of this study was to assess the construct validity of the Curiosity and Exploration Inventory II (CEI-II) in Indonesia.Design and Methods: The study included 256 undergraduate students who lived in Indonesia, mean age 19.8 years old. The CEI-II measures stretching and embracing using 11 items. The English version of CEI-II was translated into Bahasa. The Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC) were addressed to examine internal consistency reliability and the test-retest reliability. To evaluate construct validity, exploratory factor analysis (EFA) was used to assess factor structure and confirmatory factor analysis (CFA) was used to evaluate the structural model fit of the CEI-II Indonesia version.Results: The study showed Cronbach’s alpha for the internal consistency of the overall CEI-II Indonesia version was 0.77. The ICC for the test-retest reliability ranged between 0.753-0.829. EFA showed adequate with the Kaiser-Meyer-Olkin value of 0.86 and the Bartlett’s test of sphericity was statistically significant. CFA tested the second-order model with two-order factors and showed a model fit.Conclusions: The CEI-II Indonesia version indicated acceptable construct validity to evaluate curiosity in Indonesia.

Abstract Background Patient enablement is a core tenet of patient-centred and holistic primary care. The Patient Enablement Instrument (PEI) is a transitional measure limited in its ability to measure changes over time. A modified version, PEI-2, has been developed to measure enablement at a given time-point without comparison to a recalled baseline. Objective To assess the validity, reliability, sensitivity and responsiveness of PEI-2. Methods PEI-2 was modified from the Chinese PEI to assess enablement over 4 weeks in a prospective cohort study nested within a community support programme [Trekkers Family Enhancement Scheme (TFES)] in Hong Kong. Construct validity was assessed by factor analysis and convergent validity by Spearman’s correlations with health-related quality of life and depressive symptoms. Internal reliability was assessed using Cronbach’s alpha. Test–retest reliability was assessed by intraclass correlation (ICC), responsiveness by 12–24-month change in PEI-2 score and sensitivity by differences in change of PEI-2 score between TFES participants and a control group. Results PEI-2 demonstrated construct validity with all items loading on one factor (factor loadings &gt;0.7). Convergent validity was confirmed by significant correlations with 12-item Short Form Questionnaire, version 2 (r = 0.1089–0.1919) and Patient Health Questionnaire-9 (r = −0.2030). Internal reliability was high (Cronbach’s alpha = 0.9095) and test–retest reliability moderate (ICC = 0.520, P = 0.506). Significant improvements in PEI-2 scores among the TFES group suggested good responsiveness (P &lt; 0.001). The difference in change of PEI-2 scores between TFES and control was significant (P = 0.008), indicating good sensitivity. Conclusions This study supports the validity, reliability, sensitivity and responsiveness of PEI-2 in measuring changes in enablement, making it a promising tool for evaluating enablement in cohort and intervention studies.

Background and PurposePoor dietary practices are linked to many chronic diseases. The purpose of this validation study was to develop a psychometrically sound instrument that can be administered by health practitioners to measure dietary barriers.MethodsThe Dietary Health Status (DHS) instrument, designed to measure dietary barriers is comprised of items in the National Health and Nutrition Examination Survey-What We Eat in America datasets. Content validity was established for DHS using an expert review process. Principal component analysis (PCA) was then used to assess validity and reliability as determined by Cronbach's alpha values.ResultsThe PCA supported a 10-component solution, explaining 61% of the total variance. Cronbach's alpha was .67 for the entire instrument, ranging from .55 to .87 for the 10 subscales.ConclusionResults suggest the instrument had sufficient construct and internal validity. This exploratory study is an important first step in validating the DHS instrument.

Psychometric evaluations were performed on a self-perceived localization disabilities and handicaps questionnaire. Twenty individuals with normal hearing bilaterally, twenty with profound unilateral hearing impairment (UHI), and ten with any degree of bilateral hearing impairment participated. Each subject completed the questionnaire. Comparisons of the responses of the subjects with normal hearing and those with UHI revealed significant differences among the groups for both disabilities and handicaps, establishing construct validity. Cronbach's Alpha correlational analyses of the responses of all subjects with hearing impairment revealed correlations of .900 (disabilities) and .800 (handicaps), establishing internal consistency. Each participant with hearing impairment was asked to complete the questionnaire again after three weeks. Pearson's correlational analyses of the responses at time one versus time two revealed correlations of .900 (disabilities) and .700 (handicaps), establishing test/retest reliability. This questionnaire is an appropriate tool for investigating the self-perceived localization disabilities and handicaps of individuals with hearing impairment.

Background: The importance of salutogenesis, with the focus of what creates health rather than what causes diseases, has been highlighted for a long time. This has been operationalized by Aaron Antonovsky as the Sense of Coherence (SOC-13) scale. The aim of this study was to further examine the psychometric properties of the SOC-13 in India. Methods: The present study was carried out among second-year degree students at three randomly chosen institutions at Mangalore University. Investigators assessed the appropriateness, relevance, comprehensiveness and understandability of the scale. Further, the scale was assessed by five subject experts. The SOC-13 was then pretested by administering it to peers, individuals and a few of the study subjects. Internal consistency was assessed by Cronbach’s alpha and split-half reliability. Test-retest reliability was assessed by administering the instrument to the same study participants after two weeks. Confirmatory factor analysis employing varimax rotation was employed. Results: The SOC-13 revealed a Cronbach’s alpha value of 0.76. Split-half reliability and Guttman split-half reliability were found to be 0.71 and 0.70, respectively. Test-retest reliability was found to be 0.71 ( p < 0.01). Factor analysis revealed a three-factor solution explaining 40.53% of the variation in SOC. Conclusions: SOC-13 was found to be a reliable and valid instrument for measuring SOC in an Indian context. The present study contributes to health promotion in an Indian context, and could be useful even in other developing countries and for further research in India.

Abstract Background Chronic conditions impose a major impact on quality of life and on healthcare. The Assessment of Burden of Chronic Conditions (ABCC-)tool was developed to improve experienced quality of care and quality of life by facilitating shared decision-making and self-management. It assesses the experienced burden of one or multiple conditions, and visualises and integrates the burden in daily care. However, its scale’s validity and reliability are yet unknown. The aim of this study is to evaluate whether the ABCC-scale is valid and reliable in people with Chronic Obstructive Pulmonary Disease (COPD), asthma, or Type 2 Diabetes Mellitus (T2DM). Methods The Saint George Respiratory Questionnaire (SGRQ), the Standardized Asthma Quality of Life Questionnaire (AQLQ-S), and the Audit of Diabetes Dependent Quality of Life Questionnaire (ADDQoL19) were compared to the ABCC-scale to assess convergent validity. Convergent validity was assumed when at least 75% of the postulated correlations were higher than 0.7, or between 0.3 and 0.7 for single-item subscales. To measure known-group validity, participants were categorized according to exacerbation status, depression, asthma control, insulin dependence, complications and obesity. The ABCC-scale was deemed internally consistency upon a Cronbach’s alpha ≥ 0.90 for the total scale, and ≥ 0.70 for subscales. Test-retest reliability was evaluated at a two-week interval. Results A total of 65, 62, and 60 people with COPD, asthma, T2DM respectively were included. The ABCC-scale correlated, in accordance with hypotheses, with the SGRQ (75%), AQLQ-S (100%), and ADDQoL19 (75%). Differentiation of known-groups based on the ABCC-scale was possible for all specified groups. The total score and subscores of the ABCC-scale were internally consistent with a Cronbach’s alpha of 0.90, 0.92, and 0.91 for the total score for people with COPD, asthma, and T2DM respectively. The ABCC-scale had a good test-retest reliability with an Intraclass Correlation Coefficient of 0.95, 0.93, and 0.95 for people with COPD, asthma and T2DM respectively. Conclusions The ABCC-scale is a valid and reliable questionnaire that can be used within the ABCC-tool for people with COPD, asthma or T2DM. Future research should indicate whether this also applies to people with multimorbidity, and what the effects and experiences are upon clinical 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.
