Personality disorder (PD) is increasingly categorized according to its severity, but there is no simple way to screen for severity according to ICD-11 criteria. We set out to develop the Standardized Assessment of Severity of Personality Disorder (SASPD). A total of 110 patients completed the SASPD together with a clinical assessment of the severity of personality disorder. We examined the predictive ability of the SASPD using the area under the ROC curve (AUC). Two to four weeks later, 43 patients repeated the SASPD to examine reliability. The SASPD had good predictive ability for determining mild (AUC = 0.86) and moderate (AUC = 0.84) PD at cut points of 8 and 10, respectively. Test-retest reliability of the SASPD was high (intraclass correlation coefficient = 0.93, 95% CI [0.88, 0.96]). The SASPD thus provides a simple, brief, and reliable indicator of the presence of mild or moderate PD according to ICD-11 criteria.

Distress Scale

Background: Patients with heart failure can experience thirst distress. However, there is no instrument to measure this in patients with heart failure. The aim of the present study was to develop the Thirst Distress Scale for patients with Heart Failure (TDS-HF) and to evaluate psychometric properties of the scale. Methods and results: The TDS-HF was developed to measure thirst distress in patients with heart failure. Face and content validity was confirmed using expert panels including patients and healthcare professionals. Data on the TDS-HF was collected from patients with heart failure at outpatient heart failure clinics and hospitals in Sweden, the Netherlands and Japan. Psychometric properties were evaluated using data from 256 heart failure patients (age 72±11 years). Concurrent validity of the scale was assessed using a thirst intensity visual analogue scale. Patients did not have any difficulties answering the questions, and time taken to answer the questions was about five minutes. Factor analysis of the scale showed one factor. After psychometric testing, one item was deleted. For the eight item TDS-HF, a single factor explained 61% of the variance and Cronbach’s alpha was 0.90. The eight item TDS-HF was significantly associated with the thirst intensity score ( r=0.55, p<0.001). Regarding test-retest reliability, the intraclass correlation coefficient was 0.88, and the weighted kappa values ranged from 0.29–0.60. Conclusion: The eight-item TDS-HF is valid and reliable for measuring thirst distress in patients with heart failure.

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.

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.

The purposes of the present study were (a) to evaluate the test-retest reliability of the Price et al. (1988) 5-min walking field test, (b) to assess the validity of the test as an estimate of aerobic fitness, and (c) to derive a predictive model for estimating peak. The subjects were men and women age ≥50 with knee osteoarthritis. A high intraclass correlation coefficient was obtained in the reliability study, which included 60 subjects who did the 5-min walk twice within a maximum of 11 days. For the validity study, distances walked at the first walking trial were compared with peak values measured by a maximal treadmill test. The best predictive model included the following predictor variables: distance walked in 5 min, age, sex, and weight. Results indicate that the 5-minutc walking field test is a reliable and valid method for estimating peak in this population.

Objective: To compare psychometric properties of Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, Shoulder Pain and Disability Index (SPADI) and Constant–Murley scale, in patients with degenerative rotator cuff disease (DRCD). Design: Longitudinal cohort. Setting: One French university hospital. Methods: The scales were applied twice at one-week interval before physiotherapy and once after physiotherapy two months later. The perceived improvement after treatment was self-assessed on a numerical scale (0–4). The test–retest reliability of the DASH, SPADI and Constant–Murley scales was assessed before treatment by the intraclass correlation coefficient (ICC). The responsiveness was assessed by the paired t-test ( P < 0.05) and standardized mean difference (SMD). The correlation between the percentage of variation in scale scores and the self-assessed improvement score after treatment was measured by the Spearman coefficient. Results: Fifty-three patients were included. Twenty-six only were available for reliability. The test–retest reliability was very good for the DASH (ICC = 0.97), SPADI (0.95) and Constant–Murley (0.92). The scale score was improved after treatment for each scale ( P < 0.05). The SMD was moderate for the DASH (0.56) and SPADI (0.56) scales, and small for the Constant–Murley (0.44). The correlation between the percentage of variation in scores and self-assessed improvement score after treatment was high, moderate and not significant for the SPADI (0.59, P < 0.0001), DASH (0.42, P < 0.01) and Constant–Murley scales, respectively. Conclusion: The test–retest reliability of the DASH, SPADI and Constant–Murley scales is very good for patients with DRCD. The highest responsiveness was achieved with the SPADI.

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.

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: Strength training in people with multiple sclerosis (MS) is an important component of rehabilitation, but it can be challenging for clinicians to quantify strength accurately and reliably. This study investigated the psychometric properties of a clinical strength assessment protocol using handheld dynamometry and other objective, quantifiable tests for the lower extremities and trunk in people with MS. Methods: This study determined discriminant validity between 25 participants with MS and 25 controls and between participants with MS who had higher versus lower disability; test-retest reliability across 7 to 10 days; and response stability. The protocol included handheld dynamometry measurements of ankle dorsiflexion, knee flexion and extension; hip flexion, extension, abduction, and adduction; and trunk lateral flexion. Muscular endurance tests were used to measure trunk extension, trunk flexion, and ankle plantarflexion. Results: The protocol discriminated between participants with MS and controls for all muscles tested (P &lt; .001–.003). The protocol also discriminated between low- and moderate-disability groups (P = .001–.046) for 80% of the muscles tested. Test-retest reliability intraclass correlation coefficients were high (0.81–0.97). Minimal detectable change as a percentage of the mean was 13% to 36% for 85% of muscles tested. Conclusions: This study provides evidence for the discriminant validity, test-retest reliability, and response stability of a strength assessment protocol in people with MS. This protocol may be useful for tracking outcomes in people with MS for clinical investigations and practice.

Background Therapists frequently advise the use of activity pacing as a coping strategy to manage long-term conditions (eg, chronic low back pain, chronic widespread pain, chronic fatigue syndrome/myalgic encephalomyelitis). However, activity pacing has not been clearly operationalized, and there is a paucity of empirical evidence regarding pacing. This paucity of evidence may be partly due to the absence of a widely used pacing scale. To address the limitations of existing pacing scales, the 38-item Activity Pacing Questionnaire (APQ-38) was previously developed using the Delphi technique. Objective The aims of this study were: (1) to explore the psychometric properties of the APQ-38, (2) to identify underlying pacing themes, and (3) to assess the reliability and validity of the scale. Design This was a cross-sectional questionnaire study. Methods Three hundred eleven adult patients with chronic pain or fatigue participated, of whom 69 completed the test-retest analysis. Data obtained for the APQ-38 were analyzed using exploratory factor analysis, internal and test-retest reliability, and validity against 2 existing pacing subscales and validated measures of pain, fatigue, anxiety, depression, avoidance, and mental and physical function. Results Following factor analysis, 12 items were removed from the APQ-38, and 5 themes of pacing were identified in the resulting 26-item Activity Pacing Questionnaire (APQ-26): activity adjustment, activity consistency, activity progression, activity planning, and activity acceptance. These themes demonstrated satisfactory internal consistency (Cronbach α=.72–.92), test-retest reliability (intraclass correlation coefficient=.50–.78, P≤.001), and construct validity. Activity adjustment, activity progression, and activity acceptance correlated with worsened symptoms; activity consistency correlated with improved symptoms; and activity planning correlated with both improved and worsened symptoms. Limitations Data were collected from self-report questionnaires only. Conclusions Developed to be widely used across a heterogeneous group of patients with chronic pain or fatigue, the APQ-26 is multifaceted and demonstrates reliability and validity. Further study will explore the effects of pacing on patients' symptoms to guide therapists toward advising pacing themes with empirical benefits.
