General versus domain-specific grit in the work context.

Researchers have questioned whether grit should be conceptualized and measured as a global (i.e., domain-general) or domain-specific construct. Although evidence is beginning to appear that grit in educational and sport contexts may be measured as domain-specific, it has not yet been explored in the organizational context. The objective of this research was to study the psychometric properties of grit as domain-specific for subsequently analyzing if such domain-specific grit (labor grit) improves the predictive validity of different organizational results. A sample of 326 active workers was used (Myears = 37.52; SD = 9.85). Their grit levels in the general domain and specific domain were evaluated, as well as their main personality traits and other organizational results such as work engagement and work performance. The grit instrument as domain-specific showed excellent reliability (ω = 0.92), and the unidimensionality of the instrument was confirmed. The results point to the fact that giving an organizational connotation to the grit items does not improve the predictability of the results. However, labor grit adds incremental validity over personality traits and work engagement to predict task and contextual performance (Δr2 = 0.13), but not to predict counterproductive behavior.

Are visual analogue scales valid instruments to measure psychological pain in psychiatric patients?

ObjectiveThe Psychological-Physical-Pain Visual Analogue Scale (PPP-VAS) was thought to probably help in identifying patients at risk of suicide. However, no data on its validity to measure psychological pain was available. Our main aim was to investigate the convergent validity of the PPP-VAS using two well-validated scales of psychological pain, the Orbach and Mikulincer Mental Pain scale (OMMP) and the Holden et al. Psychache Scale. MethodsThis multicentre study recruited a total of 1618 adult psychiatric inpatients and outpatients in Italy. Psychological pain was evaluated using the OMMP, Holden et al., and PPP-VAS scales. Psychiatric status, suicidal status, physical pain, depression, and hopelessness were also assessed. ResultsA structural equation model (SEM) using the items of psychological pain from the PPP-VAS showed that items loaded significantly on the psychological pain factor and showed good fit. Similarly, a second SEM model using the three scales of psychological pain showed acceptable fit and converged into a psychological pain construct. Correlations between the PPP-VAS and depression, hopelessness, and physical pain showed moderate correlations (r = 0.43 to r = 0.67). Finally, psychological pain evaluated with the PPP-VAS was significantly related with recent suicidal ideation in all patients (OR [95 % CI] = 1.07 [1.05, 1.09]) and recent suicide attempts in moderately to severely depressed patients, OR [95 % CI] = 1.01 [1.02, 1.03]. ConclusionThe PPP-VAS showed good psychometric properties in evaluating psychological pain. The characteristics of the PPP-VAS makes this scale a great option for its use in clinical practice to detect patients at risk of suicide.

Psychometric Validation of the Gambling Craving Scale in a Treatment-Seeking Sample.

The Gambling Craving Scale (GACS) is a multifaceted measure of gambling craving. Initial validation work by Young and Wohl (2009) in university student samples showed that the GACS had a three-factor structure capturing dimensions of Desire, Anticipation, and Relief. Despite its potential clinical utility as a measure of craving, the GACS has yet to be validated in people seeking treatment for gambling problems. Accordingly, we examined the psychometric properties in a sample of people (N = 209; Mage = 37.66; 62.2% female) participating in a randomized controlled trial testing a novel online treatment for problem gambling. We predicted the GACS would have a three-factor structure. In addition, we also examined measurement invariance across sex and problem gambling risk status. Finally, we assessed concurrent validity of the factors with other measures of problem gambling severity and involvement. Exploratory structural equation modeling findings supported a three-factor structure that was invariant across the groups tested. Each of the Desire, Anticipation, and Relief subscales were significant positive predictors of problem gambling severity and symptoms, and some form of gambling behaviour. Findings show the GACS is a promising scale to assess multidimensional craving experiences among people in treatment for gambling problems.

Investigating psychometric properties of short versions of the depressive experiences questionnaire: Findings from a representative large sample of Chinese adolescents

BackgroundAdolescence involves a period of swift change, including the development of personality vulnerabilities (i.e., dependency and self-criticism) that act as transdiagnostic factors to psychopathology. Over the past several decades, numerous short revisions have condensed the Depressive Experiences Questionnaire (DEQ) into more efficient measures of personality vulnerability. Prior research has investigated the psychometric properties of the short DEQs in adult and clinical samples. However, there has been insufficient exploration within adolescents, who are in addition marked by fluctuating personality vulnerabilities. MethodA representative large sample of adolescents and emerging adults in China aged 10 to 25 (N = 23,953) was administered five short DEQs, including the Revised DEQ (RevDEQ), Reconstructed DEQ (RecDEQ), Theoretical DEQ-21/12 (TDEQ-21/12) and adolescent DEQ (DEQ-A). The data was evaluated for internal consistency and criterion-related validity, while factor structure and measurement invariances across gender and age groups were analyzed by confirmatory factor analysis (CFA). A subset of the original sample (N = 2874) was retested after six months and analyzed for test-retest reliability and cross-time invariance. ResultCFA of the TDEQ-21/12 and RecDEQ supported the intended two-factor model. Good criterion-related validity, internal consistency and test-retest reliability for these three versions were found. Satisfying measurement invariances across gender, time, and age groups were established. LimitationThe study's scope was confined to non-clinical adolescent populations within China, highlighting a gap in cross-cultural and clinical applicability. ConclusionThe present study supports the use of the TDEQ-21/12 and RecDEQ as valid and concise instruments for measuring Chinese adolescent personality vulnerability.

Psychometric properties of the Danish version of the Caregiver Burden Scale: Investigating predictors and severity of burden after stroke, spinal cord injury, or traumatic brain injury.

To investigate (i) psychometric properties of the Danish version of the Caregiver Burden Scale, (ii) predictors of burden in caregivers of persons with stroke, spinal cord injury, or traumatic brain injury, and (iii) severity of caregiver burden, and compare level of severity of burden in caregivers of persons with stroke, spinal cord injury, or traumatic brain injury. Cross-sectional study. Pooled sample of 122 caregivers. Psychometric properties including internal consistency, floor and ceiling effects, inter-item and item-total correlation were investigated using the Caregiver Burden Scale. Severity of burden was compared using Fisher's exact test and ANOVA, and predictors of burden were investigated using multiple linear regression models. The total burden score exhibited good internal consistency (α = 0.93), with no floor or ceiling effects. Longer time as a caregiver was a significant predictor of higher total score. The majority (52.2%) reported a low level of caregiver burden (below cut-off of 2.00). Mean scores on the Caregiver Burden Scale were not significantly different among caregivers across diagnostic groups. Differences were found when comparing spinal cord injury caregivers with brain injury caregivers (traumatic brain injury and stroke, collectively), χ2(2) = 6.38, p = 0.04, as spinal cord injury caregivers were more likely to report low levels of burden. Good psychometric properties were reported, and most caregivers reported a low level of burden, and longer time as a caregiver was associated with higher burden. Consequently, the Caregiver Burden Scale is a valid measure to use when measuring burden in caregivers of stroke, spinal cord injury, and traumatic brain injury patients.

Psychometric properties and cultural adaptation of the Polish Version of the Gay Affirmative Practice Scale.

The lesbian, gay, bisexual, and transgender (LGBT) people often face unique medical disparities, including obstacles to accessing adequate and respectful care. The purpose of this study was to test the psychometric properties(internal consistency, reliability, and factor structure) of the Polish-language version of the Gay Affirmative Practice Scale (GAP-PL). The study was conducted over a 6-month period in 2023, from February to June, involving 329 medical students and professionals who evaluated the GAP-PL. Before testing the psychometric properties of the original Gay Affirmative Practice Scale (GAP), it was translated and adapted from the original English language version into the Polish language. Authors then tested the psychometric properties of the tool on a sample of 329 participants. The internal coherence of the questionnaire was tested with the analysis of verifying factors (Confirmatory Factor Analysis). Cronbach alpha and the discriminatory power index were used as internal consistency measures. There were more female than male participants (55.32%). More than 53% of the participants were heterosexual, and the average age of the respondents was ~30 years. The internal consistency of the Polish-language version and its domains was strong with the overall Cronbach's alpha ranges for each subscale domains ranging between 0.936 and 0.949. The McDonald's omega coefficient was 0.963. The GAP-PL has excellent properties of factorial validity and can be used in research and clinical practice in Polish-speaking populations.

Validation of the Approach-Avoidance Temperament Questionnaire in Individuals with Anxiety and Depression

The Approach-Avoidance Temperament Questionnaire (ATQ) is a well-established measure assessing heightened sensitivity and reactivity to reward/positive stimuli (approach temperament) and to punishment/negative stimuli (avoidance temperament). These basic dimensions of personality are believed to be important for understanding the etiology and maintenance of anxiety and depressive disorders. Despite the ATQ’s potential utility in clinical psychology research, its psychometric properties and factor structure have yet to be examined in a psychiatric sample. The aims of the present study were to 1) conduct confirmatory factor analysis to replicate the ATQ’s factor structure in individuals diagnosed with an anxiety or depressive disorder (N = 244), 2) assess internal consistency and convergent and divergent validity, and 3) explore differences in approach and avoidance temperaments in individuals with versus without a diagnosis of anxiety or depression. Results confirmed the original two-factor structure of the ATQ in a clinical sample, with approach and avoidance temperaments representing orthogonal dimensions. The measure demonstrated strong internal consistency, convergent and divergent validity, and predictive validity. Individuals with anxiety and depression scored higher on avoidance items and lower on approach items compared to those without clinical diagnoses. This study supports the use of the ATQ in clinical populations.

The Ottawa resident observation form for nurses (O-RON): evaluation of an assessment tool’s psychometric properties in different specialties

BackgroundWorkplace-based assessment (WBA) used in post-graduate medical education relies on physician supervisors’ feedback. However, in a training environment where supervisors are unavailable to assess certain aspects of a resident’s performance, nurses are well-positioned to do so. The Ottawa Resident Observation Form for Nurses (O-RON) was developed to capture nurses’ assessment of trainee performance and results have demonstrated strong evidence for validity in Orthopedic Surgery. However, different clinical settings may impact a tool’s performance. This project studied the use of the O-RON in three different specialties at the University of Ottawa.MethodsO-RON forms were distributed on Internal Medicine, General Surgery, and Obstetrical wards at the University of Ottawa over nine months. Validity evidence related to quantitative data was collected. Exit interviews with nurse managers were performed and content was thematically analyzed.Results179 O-RONs were completed on 30 residents. With four forms per resident, the ORON’s reliability was 0.82. Global judgement response and frequency of concerns was correlated (r = 0.627, P < 0.001).ConclusionsConsistent with the original study, the findings demonstrated strong evidence for validity. However, the number of forms collected was less than expected. Exit interviews identified factors impacting form completion, which included clinical workloads and interprofessional dynamics.

Cross-cultural adaptation and psychometric properties of the Italian version of the Patient-Specific Functional Scale (PSFS) in subjects with shoulder pain

Purpose To cross-culturally adapt the Patient-Specific Functional Scale (PSFS) into Italian and study its classic psychometric properties in subjects with shoulder pain (SP). Materials and Methods The PSFS was translated into Italian and administered to 109 SP subjects. Acceptability (time to administer, floor and ceiling effects), reliability (internal consistency [Cronbach’s alpha], test-retest reliability [Intraclass Correlation Coefficient (ICC)], and measurement error [Standard Error of Measurement (SEM), Minimal Detectable Change, (MDC)]), were assessed. Moreover, construct validity was investigated through a-priori hypothesis testing, comparing the PSFS with the Disability of the Shoulder, Arm and Hand (DASH) scale, 36-item Short Form Health Survey (SF-36) and Numeric Pain Rating scale (NPRS). Results The PSFS was successfully adapted into Italian, and its acceptability was satisfied. Internal consistency was high (Cronbach’s alpha = 0.925), and test-retest reliability was good (ICC = 0.866, 95% CI = 0.749–0.931). A SEM of 0.7 points and an MDC of 1.9 points were obtained. We observed moderate evidence for construct validity, with 4/6 correlations between other measures being respected. Conclusion This study provided reliability and validity of the PSFS in a sample of Italian SP subjects. Future studies should assess the responsiveness of using the PSFS as an outcome measure to capture clinical changes after treatment.

The psychometric properties of the modified fear of falling avoidance behavior questionnaire in Parkinson's disease and older adults.

The Fear of Falling Avoidance Behavior Questionnaire (FFABQ) has good psychometric properties. However, we have recently modified the FFABQ (mFFABQ) to improve the clarity of the questions and Likert responses. This study aimed to examine the reliability and validity of this modified version in older adults and people with Parkinson's disease (PD). A total of 88 participants, 39 with PD (age = 72.2 ± 9.5; 29 males, 10 females) and 49 older adults (age = 72.8 ± 5.0; 13 males, 36 females), answered the mFFABQ twice, separated by 1 week, for test-retest reliability. Construct validity was evaluated through correlational analyses with fall history, Activities-Specific Balance Confidence Scale (ABC), Berg Balance Scale (BBS), Timed Up and Go, 30-Second Sit to Stand, Sensory Organization Test, Zung Anxiety Scale, Beck Depression Inventory, Consequences of Falling Questionnaire (CoFQ), and average daily activity levels using an activity monitor. The mFFABQ had good overall test-retest reliability (intraclass correlational coefficient [ICC] = 0.822; older adult ICC = 0.781, PD ICC = 0.806). The mFFABQ correlated with fall history (r = -0.430) and exhibited high correlation with the ABC (rho = -0.804) and moderate correlations with CoFQ (rho = 0.582) and BBS (rho = -0.595). The mFFABQ also correlated with time stepping (rho = -0.298) and number of steps (rho = -0.358). These results provide supportive evidence for the reliability and validity of the mFFABQ in older adults and people with PD, which supports its suitability as a clinical and research tool for the assessment of fear of falling avoidance behavior.

Comparing Self-Report Fatigue Assessment Tools for Adults with Cerebral Palsy in a Danish Context

ABSTRACT Purpose: Many youth and adults with Cerebral Palsy (CP) experience high levels of fatigue. This study aimed to compare three fatigue self-report questionnaires to guide clinicians. Method: Thirty youth and adults (age range 17–64) with CP were assessed with Danish versions of the Fatigue Impact and Severity Self-Assessment questionnaire, the Modified Mental Fatigue Scale, and the Multidimensional Fatigue Inventory. Psychometric properties were investigated. Rank order and classification models were compared across questionnaires. Results: The Reduced Motivation and Physical Fatigue subscales of the Multidimensional Fatigue Inventory showed inadequate internal consistency. Participants were frequently ranked differently with the questionnaires. There were issues related to the conceptualization of physical fatigue. Conclusion: The choice of assessment tool should be based on assessment purpose as the questionnaires assess different aspects of fatigue severity, impact, and management. Also, test selection can have important implications on the conclusions that are made about fatigue type and severity.

Evaluating empathy level amongst the dental students using jefferson scale of physician empathy- health professional students

BackgroundEmpathy is described as one’s ability to perceive and apprehend another person’s feelings, situation, emotions, and problems as their own. Empathetic behavior increases patients’ satisfaction, reduces discomfort, and helps with patient’s satisfaction.ObjectiveTo evaluate the psychometric properties of the Jefferson Empathy Scale and compare the measure of invariance within genders and amongst the public and private sector dental students.MethodThis cross-sectional study utilized JSE-HPS version for research purpose. An exploratory factor analysis was performed to detect underlying factors. Reliability of the study tool was evaluated using Cronbach alpha test. Mann Whitney U test was used to compare the differences in scores between genders and among public and private university students while Student’s t analysis compared the scores according to different domains. The level of significance was ≤ 0.05.ResultsFemales demonstrated higher empathy levels (88.52 ± 14.19) along with private institute students (88.46 ± 13.98). Perspective taking and compassionate care domain was also scored highest by the females (31.73 ± 6.49 & 29.31 ± 6.22) and among second year students (33.30 ± 7.11 & 30.50 ± 7.16). PCA analysis extracted 4 factors namely (i) Health-care-provider’s sense of humor contributed to improved outcome (ii) Health-care provider’s understanding of patients’ feelings and of their families influences treatment outcomes (iii) Understanding body language is as important as verbal communication and (iv) Patients feel better when their feelings are understood, which accounted for the 59.51% of the total variance.ConclusionThe findings revealed that students from private institute and females demonstrated higher empathy score. Moreover, the Jefferson Scale of Empathy (JSE) was found to be a reliable and validated tool for assessment of empathy in our sample population.

Psychometric Evaluation of the Chinese Version of the Family Accommodation Scale for Obsessive–Compulsive Disorder Patient Version

This study aimed to examine the psychometric properties of the Chinese version of the family accommodation scale for obsessive–compulsive disorder (OCD) patient version (FAS-PV). A total of 171 adult OCD patients and 145 family members were enrolled in the present study. The majority of the adult OCD patients (89.5%) reported engaging in at least one accommodating behavior in the past week. The FAS-PV comprised three components that included (a) direct participation and facilitation, (b) provision of reassurance and assumption, and (c) modification of routines and avoidance. The FAS-PV demonstrated excellent internal consistency. The correlation between the total FAS-PV score and the criteria measure demonstrated excellent convergent validity when assessing the OCD symptom severity, global functioning, family functioning, and functioning impairment. The findings supported that the FAS-PV could be used widely in evaluating and identifying the accommodating behavior both in clinical and in research settings, especially in adult OCD patients who usually present to the clinic alone.

Cancer-Specific Health Utilities: Evaluation of Core Measurement Properties of the EORTC QLU-C10D in Lung Cancer Patients-Data from Four Multicentre LUX-Lung Trials, Applying Six Country Tariffs.

Cost-utility analysis generally requires valid preference-based measures (PBMs) to assess the utility of patient health. While generic PBMs are widely used, disease-specific PBMs may capture additional aspects of health relevant for certain patient populations. This study investigates the construct and concurrent criterion validity of the cancer-specific European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Utility-Core 10 dimensions (QLU-C10D) in non-small-cell lung cancer patients. We retrospectively analysed data from four multicentre LUX-Lung trials, all of which had administered the EORTC Quality of Life Questionnaire (QLQ-C30) and the EQ-5D-3L. We applied six country-specific value sets (Australia, Canada, Italy, the Netherlands, Poland, and the United Kingdom) to both instruments. Criterion validity was assessed via correlations between the instruments' utility scores. Correlations of divergent and convergent domains and Bland-Altman plots investigated construct validity. Floor and ceiling effects were assessed. The comparison of the EORTC QLU-C10D and EQ-5D-3L produced homogenous results for five of the six country tariffs. High correlations of utilities (r > 0.7) were found for all country tariffs except for the Netherlands. Moderate to high correlations of converging domain pairs (r from 0.472 to 0.718) were found with few exceptions, such as the Social Functioning-Usual Activities domain pair (max. r = 0.376). For all but the Dutch tariff, the EORTC QLU-C10D produced consistently lower utility values compared to the EQ-5D-3L (x̄ difference from -0.082 to 0.033). Floor and ceiling effects were consistently lower for the EORTC QLU-C10D (max. 4.67% for utilities). The six country tariffs showed good psychometric properties for the EORTC QLU-C10D in lung cancer patients. Criterion and construct validity was established. The QLU-C10D showed superior measurement precision towards the upper and lower end of the scale compared to the EQ-5D-3L, which is important when cost-utility analysis seeks to measure health change across the severity spectrum.

Development and Psychometric Evaluation of a Novel Measure of Nicotine E-cigarette Withdrawal for use with Adolescents and Young Adults.

Nicotine withdrawal is a well-established construct that prompts continued nicotine product use and contributes to failed cessation efforts. Despite ongoing public health concerns about nicotine e-cigarette use in adolescents and young adults (AYAs), no psychometrically-sound measure of nicotine e-cigarette withdrawal exists for this population. A mixed methods approach comprising a literature review to identify existing nicotine withdrawal items; subject matter expert feedback on existing items and novel item generation; cognitive interviews assessing the measure's instructions, items, and response options; and a large quantitative validation survey (N = 997) was employed to develop the novel retrospective measure of nicotine e-cigarette withdrawal. A 25-item solution comprising four subscales - Negative Affect, Negative Physical Symptoms, Craving, and Appetite/Food - and an Overall Withdrawal score was supported. Internal reliability was excellent (mean alpha = 0.91), and scalar measurement invariance was reached for all subgroups tested (e.g., sex, age, exclusive e-cigarette use versus dual tobacco product use, daily versus non-daily nicotine vaping). Overall Withdrawal and its subscales evidenced concurrent validity with time to first vape in the morning, e-cigarette dependence, and previous vaping cessation attempts, although not each subscale was associated with each outcome. Importantly, cross-sectional incremental validity analyses indicated that retrospective withdrawal accounted for variance in each outcome above and beyond e-cigarette dependence. The novel retrospective AYA Nicotine E-cigarette Withdrawal Scale (AYA NEWS) evidenced strong psychometric properties for use in this population. Future research can determine whether the AYA NEWS can be used to assess acute e-cigarette nicotine withdrawal. While e-cigarette use remains the most prevalent form of nicotine product use among adolescents and young adults, there are limited options for psychometrically-sound measures of e-cigarette-related constructs in this population. Withdrawal from nicotine is associated with failed cessation attempts and continued use of nicotine-containing products, making it a critical construct within tobacco-related research. This study outlines the development and preliminary psychometric evaluation of a novel, retrospective measure of nicotine e-cigarette withdrawal. Study findings support using the Adolescent and Young Adult Nicotine E-cigarette Withdrawal Scale (AYA NEWS) to assess retrospective withdrawal from nicotine e-cigarettes in young people.

A study of the validity of Spanish version of the Self-Estimated Functional Inability because of pain (SEFIP) in pre-professional dancers

ABSTRACT The aim of this research was to analyse the psychometric properties of the Spanish version of the Self-Estimated Functional Inability due to Pain Questionnaire (SEFIP) in Dance Conservatory students. For this purpose, the Self-Estimated Functional Inability Because Of Pain (SEFIP) instrument was used, translated into Spanish, validated by experts and administered to a total of 451 students from the Professional and Superior Dance Conservatories of Andalusia (418 females = 92.7%; 33 males = 7.3%) aged 10 and 48 years (M = 18.66; SD = 5.296). The structure of the instrument was then analysed using confirmatory procedures. The Spanish version of the instrument was named Cuestionario de Incapacidad Funcional Autoestimada debido al Dolor. The results show that the model that presents correct fits in the confirmatory analysis is the one-factor model. The model fit data were very good: χ2/gl = 3.37, p = .000; CFI = .94; NFI = .95; GFI = .91; RMSEA = .07 (90% CI = .603; .821). The results support the validity and reliability of this instrument in this population to be used to prevent injuries in dancers.

Psychometric Evaluation of the Thai Male Depression Risk Scale (MDRS-TH)

Previous studies have reported that males frequently suffer from major depression. However, due to the norms of masculine roles, in which emphasis is placed in displaying strength, invulnerability, and control, the ways that some men exhibit depression may differ from traditional diagnostic symptoms of major depressive disorder. To this end, the Male Depression Risk Scale (MDRS) has been developed in order to better identify those men, who experience low moods and are at risk for suicide. This study evaluated the psychometric properties of the Thai version of the MDRS (MDRS-TH). A cross-sectional study was conducted with 600 participants, who were recruited through social media (male N=300). The average age was 38.74 years. About half of the participants were married (51.5%). The majority identified themselves as Buddhist (94.66%) and had completed postgraduate education (31.16%). The samples had a variety of occupations, including farmer, employee, student, retired, own business, etc. The data were analyzed using confirmatory factor analysis, Cronbach's alpha coefficient, and criterion-related validity using Pearson's correlation. The overall analysis (N=600) found that the MDRS-TH was consistent with the empirical data (CFI=0.918, TLI=0.905, SRMR=0.05, and RMSEA=0.05). The final model consisted of 5 components: 1) emotional suppression, 2) alcohol use, 3) anger &amp; aggression, 4) somatic symptoms, and 5) risk-taking behaviors. The internal consistency of the MDRS-TH total score was 0.89, and the correlation criterion-related validity with the PHQ-9 was r=0.77. The results supported the fact that the MDRS-TH is a useful screening tool. Utilizing the MDRS-TH in primary care settings may assist to identify those men who are at risk for male-specific symptoms of depression so that early identification and intervention can be facilitated. In future studies, the generalizability of the scale would be strengthened if efforts to improve cross-cultural validation involving different cultural groups in Thailand were prioritized.

Translation, Cross-Cultural Adaptation, and Validation of the Traditional Chinese Version of the VISA-P Questionnaire.

The Victorian Institute of Sport Assessment-Patella (VISA-P) questionnaire is a widely accepted instrument for measuring the severity of symptoms and pain in patients having sustained patellar tendinopathy. To adapt the VISA-P questionnaire cross-culturally to a traditional Chinese version (VISA-P-Ch) and validate its psychometric properties. Cohort study (diagnosis); Level of evidence, 3. The VISA-P questionnaire was adapted to a traditional Chinese version following international recommended guidelines, including translation, synthesis, back translation, revision by expert committee, pretesting, and validation. The psychometric properties were tested in 15 healthy controls and 15 participants with patellar tendinopathy. Face validity was judged by the authors and participants. Known-groups validity was tested by comparing the VISA-P-Ch scores between symptomatic and asymptomatic participants using an independent t test. Concurrent validity was determined by comparing the Blazina classification of the participants against VISA-P-Ch scores using the Spearman correlation coefficient. Test-retest reliability was assessed by calculating the intraclass correlation coefficient (ICC) following a 24- to 48-hour interval. Internal consistency was determined by the Cronbach alpha. The expert committee and participants reported good face validity of the VISA-P-Ch. Significantly higher scores were found in the control group than in the patellar tendinopathy group (98.47 ± 3.04 vs 65 ± 11.9; P < .001). Concurrent validity showed a high correlation between VISA-P-Ch and the Blazina classification system (r = -0.899; P < .01). The test-retest reliability was excellent (ICC = 0.964). Internal consistency was found to be good for both the first and second assessments (Cronbach α = 0.834 and 0.851). The VISA-P-Ch was proven to be a reliable and valid questionnaire with similar psychometric properties as the original VISA-P.

Psychometric testing of the Chinese version of the Perceived Maternal Parenting Self-Efficacy Scale among postpartum women.

Maternal parenting self-efficacy plays a critical role in facilitating positive parenting practices and successful adaption to motherhood. The Perceived Maternal Parenting Self-Efficacy Scale (PMPS-E), as a task-specific measure, confirms its psychometric properties in cultural contexts. Compared with other tools, the advantages of the PMPS-E are as follows: (i) specific context or time period during the lifespan of a child, (ii) explicitly assess parenting self-efficacy across a diverse enough range of parenting tasks or activities during the perinatal/postnatal period and (iii) having robust psychometric properties. The aim of this study was to translate and determine the psychometric properties of the PMPS-E among Chinese postpartum women (C-PMPS-E). The cross-cultural adaptation process followed Beaton et al.'s intercultural debugging guidelines. A total of 471 women were included to establish the psychometric properties of the C-PMPS-E. Mothers were asked to complete the C-PMPS-E, Edinburgh Postnatal Depression Scale (EPDS), the Generalized Anxiety Disorder-7 (GAD-7) and several demographic questions. The psychometric testing of the C-PMPS-E was established through item analysis, construct validity and internal consistency reliability. Item analysis showed that the critical ratios of all items were greater than 3 between the low-score group and high-score group, and all item-total correlation coefficients were greater than 0.4. The fit indices showed that the original correlated four-factor model of C-PMPS-E was observed to be an excellent fit to the data. The PMPS-E was negatively correlated with the EPDS and GAD-7 demonstrating its discriminant validity. As expected, no significant correlation was found between PMPS-E total or subscale scores and mothers' age. In addition, statistically significant differences for parity were detected for C-PMPS-E total and subscale scores with multipara having higher scores. This was taken as further evidence of the scale known-groups discriminant validity. In terms of internal consistency, the Cronbach's alpha of the C-PMPS-E total scale was 0.950, and subscales ranged from 0.76 to 0.89. Furthermore, a ROC curve analysis was conducted to establish the ability of the C-PMPS-E to distinguish between symptoms of depression and symptoms of anxiety. A cut-off value of 55 was identified that resulted in good specificity and fair sensitivity. The C-PMPS-E is a reliable and valid tool to assess maternal parenting self-efficacy in a Chinese context.

Prolonged grief disorder in an inpatient psychiatric sample: psychometric properties of a new clinical interview and preliminary prevalence.

Prolonged Grief Disorder (PGD) was newly included in the ICD-11 and DSM-5-TR. It is not yet part of the standard assessments in many healthcare systems, including psychiatric wards. Because disordered grief is associated with suicidality, sleep problems and substance use disorders, an investigation into PGD in psychiatric inpatients is warranted. We interviewed N = 101 psychiatric inpatients who were admitted to the open psychiatric wards and the day hospital of a German psychiatric hospital and who had lost a person close to them. Assessments comprised clinical interviews and self-report instruments covering PGD and other mental disorders. We specifically developed the International Interview for Prolonged Grief Disorder according to ICD-11 (I-PGD-11) for the study and examined its psychometric properties. The prevalence rate of PGD among bereaved patients according to ICD-11 was 16.83% and according to DSM-5-TR 10.89%. The I-PGD-11 showed good psychometric properties (Mc Donald's ω = 0.89, ICC = 0.985). Being female, having lost a child or spouse, and unnatural or surprising circumstances of the death were associated with higher PGD scores. Approval was obtained by the ethics committee of the of the Goethe University Frankfurt (2021-62, 2023-17) and the Chamber of Hessian Physicians (2021-2730-evBO). The study was preregistered ( https://doi.org/10.17605/OSF.IO/K98MF ). We only assessed inpatients of one psychiatric clinic in Germany, limiting the generalizability of our findings. The present study underlines the importance of exploring loss and grief in psychiatric inpatients and including PGD in the assessments. Given that a significant minority of psychiatric inpatients has prolonged grief symptoms, more research into inpatient treatment programs is needed.
