Project description:BackgroundIllness perceptions involve the personal beliefs that patients have about their illness and may influence health behaviours considerably. Since an instrument to measure these perceptions for Malay population in Malaysia is lacking, we translated and examined the psychometric properties of the Malay version of the Brief Illness Perception Questionnaire (MBIPQ) in adult patients with type 2 diabetes mellitus.MethodsThe MBIPQ has nine items, all use a 0-10 response scale, except the ninth item about causal factors, which is an open-ended item. A standard procedure was used to translate and adapt the English BIPQ into Malay language. Construct validity was examined comparing item scores and scores on the Diabetes Management Self-Efficacy Scale, the Morisky Medication Adherence Scale, the World Health Organization Quality of Life-brief, the 9-item Patient Health Questionnaire, the 17-item Diabetes Distress Scale, HbA1c and the presence of complications. In addition, 2-week and 4-week test-retest reliability were studied.ResultsA total of 312 patients completed the MBIPQ. Out of this, 97 and 215 patients completed the 2- or 4-weeks test-retest reliability questionnaire, respectively. Moderate inter-items correlations were observed between illness perception dimensions (r = -0.31 to 0.53). MBIPQ items showed the expected correlations with self-efficacy (r = 0.35), medication adherence (r = 0.29), quality of life (r = -0.17 to 0.31) and depressive symptoms (r = -0.18 to 0.21). People with severe diabetes-related distress also were more concern (t-test = 4.01, p < 0.001) and experienced lower personal control (t-test = 2.07, p = 0.031). People with any diabetes-related complication perceived the consequences as more serious (t-test = 2.04, p = 0.044). The 2-week and 4-week test-retest reliabilities varied between ICCagreement 0.39 to 0.70 and 0.58 to 0.78, respectively.ConclusionsThe psychometric properties of items in the MBIPQ are moderate. The MBIPQ showed good cross-cultural validity and moderate construct validity. Test-retest reliability was moderate. Despite the moderate psychometric properties, the MBIPQ may be useful in clinical practice as it is a useful instrument to elicit and communicate on patient's personal thoughts and feelings. Future research is needed to establish its responsiveness and predictive validity.Trial registrationClinicalTrials.gov NCT02730754 registered on March 29, 2016; NCT02730078 registered on March 29, 2016.

Project description:How patients relate to the experience of their illness has a direct impact over their behavior. We aimed to assess illness perception in patients with pulmonary tuberculosis (TB) by means of the Brief Illness Perception Questionnaire (BIPQ) in correlation with patients' demographic features and clinical TB score. Our observational questionnaire based study included series of consecutive TB patients enrolled in several countries from October 2008 to January 2011 with 167 valid questionnaires analyzed. Each BIPQ item assessed one dimension of illness perceptions like the consequences, timeline, personal control, treatment control, identity, coherence, emotional representation and concern. An open question referred to the main causes of TB in each patient's opinion. The over-all BIPQ score (36.25 ± 11.054) was in concordance with the clinical TB score (p ≤ 0.001). TB patients believed in the treatment (the highest item-related score for treatment control) but were unsure about the illness identity. Illness understanding and the clinical TB score were negatively correlated (p < 0.01). Only 25% of the participants stated bacteria or TB contact as the first ranked cause of the illness. For routine clinical practice implementation of the BIPQ is convenient for obtaining fast and easy assessment of illness perception with potential utility in intervention design. This time saving effective personalized approach may improve communication with TB patients and contribute to better behavioral strategies in disease control.

Project description:BackgroundThis study aimed to adapt the Knee injury and Osteoarthritis Outcome Score- Anterior Cruciate Ligament (KOOS-ACL) into Turkish and to assess its validity and reliability.MethodsThe adaptation process involved translation, back-translation, and cultural adaptation of the questionnaire. Totally 133 patients who had a diagnosis of anterior cruciate ligament tear was recruited. The reliability of the Turkish version of the KOOS-ACL was assessed using Cronbach's alpha, item-total correlations, and ICC. EFA and CFA were performed to evaluate construct validity, supported by KMO and Bartlett's test results. Criterion validity was examined through correlations with IKDC scores, and discriminative power was assessed using an independent samples t-test.ResultsIKDC score for evaluating knee function was 59.84 ± 21.74. The composite KOOS-ACL-Tr score was 61.95 ± 25.19. Cronbach's Alpha value was found to be 0.952 demonstrating high reliability. KOOS-ACL-Tr scores showed a linear positive correlation with the time elapsed since injury and IKDC scores (p < 0.001) establishing concurrent validity.ConclusionsThe adapted Turkish version of the KOOS-ACL is a valid and reliable scale intended for use in monitoring patients with ACL injuries.

Project description:ObjectiveTo obtain adapted versions for the Spanish population of a specific version of the Revised Illness Perception Questionnaire Revised (IPQ-R(e)) and the Brief Illness Perception Questionnaire (BIPQ), conceptually and linguistically equivalent to the original questionnaires.DesignCultural adaptation of questionnaires: linguistic validation.SettingFive primary care centres and a tertiary hospital.ParticipantsA multidisciplinary team was selected. A pilot study was performed on 30 people with chronic diseases (hypertension, diabetes mellitus, stable ischaemic heart disease, asthma, chronic obstructive pulmonary disease or osteoarthritis)MethodThe project proceeded in 3 phases: I) Double forward-translation, II) Pilot study and III) Double back-translation. Three consensus meetings were held, one in each phase. Another meeting was held with one of the authors of the original questionnaire, where we knew about a short version, the BIPQ. It was also included in the study. Double forward and back-translations were performed and consensus was reached in both stages.ResultsPhase I) The majority of IPQ-R(e) items did not raise problems of translation. Phase II) In the pilot study we detected that patients found some difficulties in connection with the comprehension and self administration of some items. Therefore it was decided to employ trained interviewers, to introduce changes in the IPQ-R(e) format and vocabulary and to adapt a specific version with fewer items that solved most of these difficulties Phase III) Back-translations were very similar to the original version. The BIPQ forward and back-translation process caused no difficulties.ConclusionsAfter lingüistic validation, IPQ-R(e) and BIPQ versions conceptually and lingüistically equivalent to original instruments were obtained.

Project description:Lay abstractEarly intervention for individuals with autism spectrum disorder (ASD) is dependent on reliable methods for early detection. Screening for ASD symptoms is an important strategy in low- and middle-income countries that often lack adequate service infrastructure. This study aims to conduct preliminary evaluation of the psychometric properties of a tool developed and deployed in Nigeria called the Nigerian Autism Screening Questionnaire (NASQ). Results demonstrated that NASQ, when used as a community-based survey, has a clear factor structure with consistent measurement across age and sex, and that scores from below average to well above average are measured reliably. Future research is needed to examine the performance of this tool against confirmatory ASD diagnosis in screening and diagnostic contexts to further understand the utility and applicability of this tool in the resource-limited Nigerian setting.

Project description:OBJECTIVE:The aim of this study is to perform validity and reliability examination of the Turkish form of Acceptance and Action Diabetes Questionnaire, and to investigate whether this scale is a measurement tool for evaluation of psychological flexibility levels in a sample of patients with diabetes in Turkey. METHODS:This study was conducted with 105 patients. Turkish forms of the Beck Depression Inventory (BDI), Problem Areas in Diabetes Questionnaire (PAID), State-Trait Anxiety Inventory (STAI-I and STAI-II), Audit of Diabetes-Dependent Quality of Life (ADDQoL) and Turkish form of Acceptance and Action Diabetes Questionnaire (TAADQ) were applied. SPSS 20.0 and AMOS was used in statistical analysis. RESULTS:56.12% of the patients were female and the mean of age was 54 (SD=±9.9) years. The mean duration of education was found 7.65 (SD=3.97) years. 74.8% of the patients most of whom (83.3%, n=85) had diabetes mellitus and the mean glycemic control calculated with HbA1c was 8.02±1.91. According to the final fit indices, we found that the revised and corrected 9-item model was superior over the previous model. Cronbach Alpha coefficient of TAADQ was found as 0.836. CONCLUSION:TAADQ is a valid and reliable assessment tool in Turkish population. So TAADQ will be a powerfull tool in assessing psychological flexibility in diabetes patients.

Project description:Study objectivesto evaluate the reliability and validity of the Brief Insomnia Questionnaire (BIQ), a fully structured questionnaire developed to diagnose insomnia according to hierarchy-free Diagnostic and Statistical Manual, Fourth Edition, Text Revision (DSM-IV-TR), International Classification of Diseases-10 (ICD-10), and research diagnostic criteria/International Classification of Sleep Disorders-2 (RDC/ICSD-2) general criteria without organic exclusions in the America Insomnia Survey (AIS).Designprobability subsamples of AIS respondents, oversampling BIQ positives, completed short-term test-retest interviews (n = 59) or clinical reappraisal interviews (n = 203) to assess BIQ reliability and validity.Settingthe AIS is a large (n = 10,094) epidemiologic survey of the prevalence and correlates of insomnia.Participantsadult subscribers to a national managed healthcare plan.InterventionNoneMeasurements and resultsBIQ test-retest correlations were 0.47-0.94 for nature of the sleep problems (initiation, maintenance, nonrestorative sleep [NRS]), 0.72-0.95 for problem frequency, 0.66-0.88 for daytime impairment/distress, and 0.62 for duration of sleep. Good individual-level concordance was found between BIQ diagnoses and diagnoses based on expert interviews for meeting hierarchy-free inclusion criteria for diagnoses in any of the diagnostic systems, with area under the receiver operating characteristic curve (AUC, a measure of classification accuracy insensitive to disorder prevalence) of 0.86 for dichotomous classifications. The AUC increased to 0.94 when symptom-level data were added to generate continuous predicted-probability of diagnosis measures. The AUC was lower for dichotomous classifications based on RDC/ICSD-2 (0.68) and ICD-10 (0.70) than for DSM-IV-TR (0.83) criteria but increased consistently when symptom-level data were added to generate continuous predicted-probability measures of RDC/ICSD-2, ICD-10, and DSM-IV-TR diagnoses (0.92-0.95).Conclusionsthese results show that the BIQ generates accurate estimates of the prevalence and correlates of hierarchy-free insomnia in the America Insomnia Survey.

Project description:BackgroundsThis study aimed to assess the validity and reliability of the Turkish version of the Individual Work Performance Questionnaire (IWPQ).MethodsA total of 340 adult participants who had been working for at least 8 h a day completed the study questionnaire online. The questionnaire consisted of sections on demographics and socioeconomic characteristics, the IWPQ, and the ultrashortened version of the Utrecht Work Engagement Scale (UWES-3). Principal component analysis (PCA) with Promax rotation was conducted to assess the e three-factor structure for the Turkish version of the IWPQ. Cronbach's alpha was used to determine internal consistency. The intraclass correlation coefficient (ICC) was used to assess test-retest reliability. Spearman correlation coefficients were calculated between the IWPQ and UWES-3 scales to evaluate convergent validity.ResultsThe three factors accounted for a total variance ratio of 60.7%. Cronbach's alphas of three subscales (task performance, contextual performance, and counterproductive work behavior) were 0.894, 0.875, and 0.796, respectively. Test-retest reliability showed high agreement, with ICCs of 0.96, 0.98, and 0.91 for the respective scales. There was a statistically significant correlation between UWES-3 and the task performance subscale (ρ = 0.367 and p < 0.001), a statistically significant correlation between UWES-3 and the contextual performance subscale (ρ = 0.403 and p < 0.001), and a statistically significant correlation between UWES-3 and the CWB subscale (ρ=-0.352 and p < 0.001).ConclusionsThe Individual Work Performance Questionnaire (IWPQ) identifies work performance.The Turkish version of the IWPQ scales demonstrated validity and reliability in assessing individual work performance.

Project description:BackgroundActivities and participation play important roles in the maintenance of healthy aging. The maintenance of these factors optimizes social life to increase the quality of life with aging. However, there is a lack of questionnaires in Turkish to evaluate activity and participation among older people. This study translated and cross-culturally adapted the Oxford Participation and Activities Questionnaire (Ox-PAQ) into Turkish and investigated its psychometric properties in the older adult population.MethodsThe Turkish version of the Ox-PAQ was produced after a translation and back-translation process. The Ox-PAQ was administered to 230 and 60 individuals for construct validity and reliability analyses, respectively. To assess the test-retest reliability of the Turkish Ox-PAQ, the questionnaire was reapplied 7 days after the first interview. Cronbach's alpha (α) was used to evaluate the internal consistency. The Ox-PAQ was compared to the Short Form-12 and the Katz Index of Independence in Activities of Daily Living Scale to determine its validity.ResultsThe Turkish Ox-PAQ showed excellent internal consistency (α=0.98) and test-retest reliability (intraclass correlation coefficient=0.98, 0.96, and 0.97 for the subscales of routine activity level, social engagement, and emotional well-being, respectively). In the validity analysis, factor analysis demonstrated a probable structure of the three factors that together explained 66.35% of the total variance. The Turkish Ox-PAQ was correlated with the other comparison measures used in this study.ConclusionThe Turkish Ox-PAQ is a reliable and valid questionnaire to evaluate the participation and activity levels of older people (Clinical Trial Number: NCT04368754).

Project description:This study elucidates the cross-cultural adaptation, reliability, and validity of the Turkish version of the Smart Tools Proneness Questionnaire (STP-Q), designed to probe into individuals' engagement with smart tools within the Turkish cultural milieu. Undertaking a rigorous adaptation process, this investigation aimed to ensure the questionnaire's relevance and intelligibility, subsequently, assessing its psychometric properties within a cohort of 387 participants. The exploratory factor analysis revealed a tripartite structure that reflects the original instrument, covering utilitarian use, hedonic and social use, and the inclination to delegate tasks. This congruity underscores the STP-Q's adeptness in capturing the complex dimensions of smart tool interaction across various contexts. Demonstrated by a Cronbach's alpha of 0.954 and a test-retest reliability index of 0.851, the results affirm the questionnaire's exceptional internal consistency and significant temporal stability. Further, the execution of convergent validity assessments alongside the E-Learning Readiness Scale and the Nomophobia Questionnaire augmented the STP-Q's validity, unveiling correlations that delineate the intricate interrelations among smart tool proneness, e-learning readiness, and nomophobia. Conclusively, the STP-Q distinguishes itself as a reliable and valid instrument for gauging tendencies towards smart tool use among the Turkish populace, providing profound insights into digital behavior across different cultural backgrounds. Its confirmed three-factor structure and robust psychometric attributes render it an indispensable resource for both individual assessments and expansive digital behavior investigations, enabling cross-cultural comparisons and enhancing our understanding of technology engagement dynamics.
