The English version of the Independent Television Commission-Sense of Presence Inventory (ITC-SOPI), which was developed in 2001 to measure how involved or present participants are when experiencing different media, has substantial psychometric evidence. This study was used to translate and validate the ITC-SOPI in interactive virtual environments among the Chinese population. We used the forward-backward translation procedure. An expert panel reviewed the translated ITC-SOPI until the Chinese version of the ITC-SOPI was finalized. A total of 210 participants (133 males and 77 females), with a mean age of 23.05 years ( SD = 3.56, range = 17–47), completed the Chinese ITC-SOPI. The following psychometric properties were examined: factor structure, internal consistency, test–retest reliability, and convergent validity. Confirmatory factor analysis (CFA) showed a good fit (χ2 /df = 1.70, Tucker–Lewis Index [TLI] = 0.91, comparative fit index [CFI] = 0.92, root mean square error of approximation [RMSEA] = 0.058) of the four-factor model (spatial presence, engagement, ecological validity, and negative effects). For each factor, the Chinese ITC-SOPI had high internal consistency (Cronbach’s α ranging from 0.75 to 0.87) and test–retest reliability (intraclass correlation coefficient ranging from 0.82 to 0.91). Significant correlations were identified between all factors and the Interpersonal Reactivity Index-C (IRI-C) and the Generalized Anxiety Disorder-7 (GAD-7). The Chinese ITC-SOPI had good psychometric properties, suggesting that it is a reliable and valid tool for evaluating media users’ sense of presence in a Chinese-speaking context.

Abstract Background: Outcome measurement is an essential part of the evaluation of palliative care and the measurements need to be reliable, valid and adapted to the culture in which they are used. The Integrated Palliative Outcome Scale (IPOS) is a widely used tool for assessing personal-level outcomes in palliative care. The aim of this study was to provide Czech version of IPOS and asses its psychometric properties. Methods: Patients receiving palliative care in hospice or hospitals completed the IPOS. The reliability of Czech IPOS was tested with Cronbach alpha (for internal consistency), the intraclass correlation coefficient for total IPOS score and weighted Kappa (for test-retest reliability of individual items). Factor analysis was used for elucidating the construct (Exploratory Factor Analysis). Convergent validity was tested with correlation analysis (Spearman correlation) in a part of the sample, who completed also the Edmonton Symptom Assessment System (ESAS) and the Palliative Performance Scale (PPS). Results: The sample consisted of 140 patients (mean age 72; 90 women; 81 % oncological disease). The Cronbach alpha was 0.789; intraclass correlation was 0.88. The correlations of IPOS with ESAS was R= 0.4 and PPS R= -0.2. Exploratory factor analysis revealed a 2-factor solution on our data. The first factor covers emotional and information needs and the second factor covers physical symptoms. Conclusion: Czech IPOS has very good reliability regarding both internal consistency and test-retest reliability. Together with an item analysis results, we can conclude that the Czech adaptation of the tool was successful. The convergent validity needs to be assessed on the larger sample and the proposed 2-factor internal structure of the questionnaire has to be confirmed by using CFA.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P < 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

Background: The Sexual Interest and Desire Inventory Female (SIDI-F) is a clinician-administered scale that allows for a comprehensive assessment of symptoms related to Hypoactive Sexual Desire Dysfunction (HSDD). As self-report questionnaires may facilitate less socially desirable responding and as time and resources are scarce in many clinical and research settings, a self-report version was developed (SIDI-F-SR). Aim: To investigate the agreement between the SIDI-F and a self-report version (SIDI-F-SR) and assess psychometric properties of the SIDI-F-SR. Methods: A total of 170 women (Mage=36.61, SD=10.61, range=20-69) with HSDD provided data on the SIDI-F, administered by a clinical psychologist via telephone, and the SIDI-F-SR, delivered as an Internet-based questionnaire. A subset of 19 women answered the SIDI-F-SR twice over a period of 14 weeks. Outcomes: Intraclass correlation as well as predictors of absolute agreement between SIDI-F and SIDI-F-SR, as well as internal consistency, test-retest reliability, and criterion-related validity of the SIDI-F-SR were examined. Results: There was high agreement between SIDI-F and SIDI-F-SR (ICC=.86). On average, women scored about one point higher in the self-report vs. the clinician-administered scale. Agreement was higher in young women and those with severe symptoms. Internal consistency of the SIDI-F-SR was acceptable (α=.76) and comparable to the SIDI-F (α=.74). When corrections for the restriction of range were applied, internal consistency of the SIDI-F-SR increased to .91. Test-retest-reliability was good (r=.74). Criterion-related validity was low but comparable between SIDI-F and SIDI-F-SR.

Background Occupational balance, a fundamental concept in occupational therapy, is the arrangement of right amount and variety of occupations contributes to a person’s health and well-being. This study was aimed to investigate the reliability and validity of the Chinese version of the Occupational Balance Questionnaire (OB-Quest) for people with insomnia. Methods The OB-Quest was translated into traditional Chinese and reviewed by an expert panel for content validity, cultural relevance and translation accuracy. Internal consistency, factor analysis and convergent validity, as well as test–retest reliability, were explored. Results The participants (n = 205), 115 adults with insomnia and 90 adults without insomnia, completed a survey of demographic background, the Chinese version of OB-Quest and the Chinese Insomnia Severity Index (C-ISI). The Chinese version of OB-Quest demonstrated excellent test–retest reliability (ICC= 0.98) and good internal consistency (Cronbach’s α  =  0.80). Factor analysis indicated that a single-factor solution explained 42% of the variance, and 9 out of 10 items had a factor loading of 0.4 or above. The Chinese version of OB-Quest had significant correlations with C-ISI (r = –0.88; p < 0.001). A significant difference was found in occupational balance between groups with different levels of insomnia severity and without insomnia (F = 169.72; p < 0.001). As in a previous study, age, living environment and life role had no significant relationship with occupational balance. Conclusion The Chinese version of OB-Quest is a short, easy to understand and culturally relevant assessment for Chinese. It demonstrates satisfactory psychometric properties and had significant correlations with insomnia.

ObjectiveEven though continuity is essential after discharge, there is a lack of reliable questionnaires to measure and assess patients’ perceptions of continuity of care. The Patient Continuity of Care Questionnaire (PCCQ) addresses the period before and after discharge from hospital. However, previous studies show that the factor structure needs to be confirmed and validated in larger samples, and the aim of this study was to evaluate the psychometric properties of the PCCQ with focus on factor structure, internal consistency and stability.DesignA psychometric evaluation study. The questionnaire was translated into Swedish using a forward–backward technique and culturally adapted through cognitive interviews (n=12) and reviewed by researchers (n=8).SettingData were collected in four healthcare settings in two Swedish counties.ParticipantsA consecutive sampling procedure included 725 patients discharged after hospitalisation due to angina, acute myocardial infarction, heart failure or atrial fibrillation.MeasurementTo evaluate the factor structure, confirmatory factor analyses based on polychoric correlations were performed (n=721). Internal consistency was evaluated by ordinal alpha. Test–retest reliability (n=289) was assessed with intraclass correlation coefficient (ICC).ResultsThe original six-factor structure was overall confirmed, but minor refinements were required to reach satisfactory model fit. The standardised factor loadings ranged between 0.68 and 0.94, and ordinal alpha ranged between 0.82 and 0.95. All subscales demonstrated satisfactory test–retest reliability (ICC=0.76–0.94).ConclusionThe revised version of the PCCQ showed sound psychometric properties and is ready to be used to measure perceptions of continuity of care. High ordinal alpha in some subscales indicates that a shorter version of the questionnaire can be developed.

BackgroundThe Mental Health Recovery Star (MHRS) is a popular outcome measure rated collaboratively by staff and service users, but its psychometric properties are unknown.AimsTo assess the MHRS's acceptability, reliability and convergent validity.MethodA total of 172 services users and 120 staff from in-patient and community services participated. Interrater reliability of staff-only ratings and test–retest reliability of staff-only and collaborative ratings were assessed using intraclass correlation coefficients (ICCs). Convergent validity between MHRS ratings and standardised measures of social functioning and recovery was assessed using Pearson correlation. The influence of collaboration on ratings was assessed using descriptive statistics and ICCs.ResultsThe MHRS was relatively quick and easy to use and had good test–retest reliability, but interrater reliability was inadequate. Collaborative ratings were slightly higher than staff-only ratings. Convergent validity suggests it assesses social function more than recovery.ConclusionsThe MHRS cannot be recommended as a routine clinical outcome tool but may facilitate collaborative care planning.

A modified version of the Dementia Worry Scale (DWS) used the terminology “Alzheimer’s disease and related dementias” (versus the DWS’ use of “dementia”). Two studies investigated psychometric properties of the modified DWS (MDWS). Study 1 compared the psychometric properties of the DWS and MDWS; both versions had single factor structures and exhibited excellent internal consistency (αs ≥ .95). The MDWS exhibited greater test-retest reliability after a 4-week interval (DWS r = .68; MDWS r = .90). In Study 2, the MDWS again displayed a single factor structure, excellent internal consistency (α = .95), and good test-retest reliability after an 8-week interval (r = .78). Additionally, results support convergent validity between the MDWS and fear of dementia, subjective memory, general anxiety, health anxiety, and neuroticism. The MDWS is psychometrically consistent with the DWS, maintains strong test-retest reliability, and is appropriate for use in cross-sectional and longitudinal research.

Introduction: There is a need to have appropriate information about the ability of Parkinson's disease (PD) patients to perform cognitive instrumental activities of daily living (IADL). The purpose of the present study was to assess the psychometric properties of the Persian version of the Penn Parkinson's Daily Activities Questionnaire-15 (PDAQ-15). Methods: A total of 165 knowledgeable informants of PD patients completed the PDAQ-15. The Clinical Dementia Rating Scale, Hoehn and Yahr staging, Hospital Anxiety and Depression Scale (HADS) and Lawton IADL scale were included in the study. Internal consistency and test-retest reliability were evaluated by Cronbach's alpha coefficient and intraclass correlation coefficient (ICC), respectively. To examine the dimensionality of the questionnaire, exploratory factor analysis was used. The construct validity was assessed using Spearman rank correlation test. To assess the discriminative validity, PDAQ-15 scores were compared across cognitive stages. Results: The PDAQ-15 showed strong internal consistency (Cronbach's α = 0.99) and test-retest reliability (ICC= 0.99). Only one dimension identified for the PDAQ-15 in the factor analysis. There was strong correlation between PDAQ-15 with depression domain of HADS scale and Lawton IADL scale. (rs = |0.71–0.95|). The correlation of PDAQ-15 with anxiety domain of HADS scale was moderate (rs = 0.66). Discriminative validity analysis showed that the PDAQ-15 has significant power to discriminate between PD patients across cognitive stages. Conclusion: These results suggest that the PDAQ-15 is a valid and reliable PD-specific instrument that can be useful in clinical and research settings.

Background: Construct of Alexithymia is important for understanding psychopathology that its assessment is of high interest as persons with difficulty in processing their emotions (either positive and negative) are more vulnerable to psychopathology problems. Objectives: The current study aimed to determine the psychometric properties of the Perth Alexithymia questionnaire (PAQ), and to describe appropriate measures for the field of clinical psychology and psychiatry. Methods: The Persian version of the PAQ was produced through forward translation, reconciliation, and back translation. The study population was all staff (soldiers) of the army force in Tehran, Iran, in 2018 - 2019. Two hundred and fifty four soldiers were selected by convenience sampling method. The following questionnaires were used to collect data: the PAQ, The Deliberate Self-Harm inventory (DSHI), Borderline Personality scale (STB), Cognitive Flexibility inventory (CFI), and Self-Compassion scale (SCS) short-form. The construct validity of the PAQ was evaluated using confirmatory factor analysis, divergent, and convergent validity. Internal Consistency and test-retest reliability (2 weeks’ interval) were applied to evaluate reliability. Data were analyzed using LISREL (version 8.8) and SSPS (version 22). Results: PAQ and its subscales were found as valid and reliable measures, with good internal consistency and good test-retest reliability. The PAQ showed good internal consistency (Cronbach’s α = 0.91). Concerning the convergent validity, PAQ and its subscales showed a significant positive correlation with self-report measures of DSHI and STB (P < 0.05). However, they were negatively correlated with Self-Compassion scale (SCS) short-form and CFI (P < 0.05), which demonstrated a good divergent validity. Moreover, while the results of this study support the five-factor models of the PAQ (RMSEA = 0.08, NFI = 0.94, CFI= 0.95), the two-factor model does not fit the data. Conclusions: The PAQ showed good validity and reliability and can be useful for evaluating Alexithymia in the army force samples. The PAQ can be considered promising as a measure in Alexithymia-related research and clinical settings.
