A Comparison of Test-Retest Reliability and Practice Effects of Short Portable Mental State Questionnaire and Montreal Cognitive Assessment in Patients with Stroke.

OBJECTIVE: To compare the test-retest reliabilities and minimal detectable change (MDC) of the Short Portable Mental State Questionnaire (SPMSQ) and the Montreal Cognitive Assessment (MoCA) in patients with stroke. METHODS: 63 patients were recruited from 1 medical center. The SPMSQ and MoCA were administered twice, 2 weeks apart. RESULTS: Both measures showed high intraclass correlation coefficients (SPMSQ: 0.87; MoCA: 0.89) and acceptable MDC%s (SPMSQ: 14.8%; MoCA: 19.6%). A small correlation (r = 0.30) was found between the absolute difference and average in each pair of assessments in the SPMSQ, which was close to the criterion of heteroscedasticity. A small practice effect was observed in the MoCA (Cohen's d = 0.30). CONCLUSION: The SPMSQ demonstrated smaller random measurement error and an absence of practice effect. When comparing the psychometric properties of the SPMSQ and MoCA as outcome measures for assessing cognitive function in patients with stroke, the SPMSQ appears to be a more suitable choice than the MoCA.

Consistency Analysis in Medical Empathy Intervention Research.

Various studies have examined the effectiveness of interventions to increase empathy in medical professionals. However, inconsistencies may exist in the definitions, interventions, and assessments of empathy. Inconsistencies jeopardize the internal validity and generalization of the research findings. The main purpose of this study was to examine the internal consistency among the definitions, interventions, and assessments of empathy in medical empathy intervention studies. We also examined the interventions and assessments in terms of the knowledge-attitude-behavior aspects. We conducted a literature search for medical empathy intervention studies with a design of randomized controlled trials and categorized each study according to the dimensions of empathy and knowledge-attitude-behavior aspects. The consistencies among the definitions, interventions, and assessments were calculated. A total of 13 studies were included in this study. No studies were fully consistent in their definitions, interventions, and assessments of empathy. Only four studies were partially consistent. In terms of knowledge-attitude-behavior aspects, four studies were fully consistent, two studies were partially consistent, and seven studies were inconsistent. Most medical empathy intervention studies are inconsistent in their definitions, interventions, and assessments of empathy, as well as the knowledge-attitude-behavior aspects between interventions and assessments. These inconsistencies may have affected the internal validity and generalization of the research results.

Development of a Rasch-Calibrated Test for Assessing Implied Meaning in Patients With Schizophrenia.

IMPORTANCE: Patients with schizophrenia tend to have severe deficits in theory of mind, which may limit their interpretation of others' behaviors and thereby hamper social participation. Commonly used measures of theory of mind assess the ability to understand various social situations (e.g., implied meaning or hinting, faux pas), but these measures do not yield valid, reliable, and gender unbiased results to inform interventions for managing theory-of-mind deficits. We used understanding of implied meaning, which appears to be a unidimensional construct highly correlated with social competence, as a promising starting point to develop a theory-of-mind assessment. OBJECTIVE: To develop a Rasch-calibrated computerized test of implied meaning. DESIGN: Cross-sectional design. SETTING: Psychiatric hospitals and community. PARTICIPANTS: 344 participants (240 patients with schizophrenia and 104 healthy adults). RESULTS: We initially developed 27 items for the Computerized Implied Meaning Test. After inappropriate items (12 misfit items and 1 gender-biased item) were removed, the remaining 14 items showed acceptable model fit to the Rasch model (infit = 0.84-1.16; outfit = 0.65-1.34) and the one-factor model (comparative fit index = .91, standardized root mean square residual = .05, root-mean-square error of approximation = .08). Most patients (81.7%) achieved individual Rasch reliability of ≥.90. Healthy participants performed significantly better on the test than patients with schizophrenia (Cohen's d = 2.5, p < .001). CONCLUSIONS AND RELEVANCE: Our preliminary findings suggest that the Computerized Implied Meaning Test may provide reliable, valid, and gender-unbiased results for patients with schizophrenia. What This Article Adds: We developed a new measure for assessing theory-of-mind ability in patients with schizophrenia that consists of items targeting the understanding of implied meaning. Preliminary findings suggest that the Computerized Implied Meaning Test is reliable, valid, and gender unbiased and may be used in evaluating patients' theory-of-mind deficits and relevant factors.

High levels of screen time were associated with increased probabilities of lagged development in 3-year-old children.

AIM: This study determined whether higher screen time was associated with the development of 3-year-old children in Taiwan. It also examined whether differences would be found between television and other screen-based media in the probability of lagged development. METHODS: We examined 2139 children aged 3 years and their parents. The association between daily screen time was assessed using multiple logistic regression analysis. All the odds ratios (ORs) were calculated using the rates of lagged developmental achievement, with the group who used screens for less than 1 h a day as the reference category. Screen time comprised television and other screen-based media, such as smartphones, touch screens, computers and laptops. RESULTS: Children who used screens for more than 3 h per day had the lowest developmental scores and highest probabilities of lagged development. The children who used other screen-based media for more than 1 h per day had greater probabilities of lagged developmental achievements (ORs 1.85-4.98, all p < 0.05) than those who watched television for the same amount of time (OR 1.41-2.77, all p < 0.05). CONCLUSION: Increased screen time was associated with higher probabilities of lagged developmental achievement in multiple development domains in 3-year-old children, particularly other screen-based media.

Animal-Assisted Therapy in Middle-Aged and Older Patients With Schizophrenia: A Randomized Controlled Trial.

Objective: Animal-assisted therapy (AAT) has the potential to improve the symptomology, negative emotions, and level of well-being in older adults, as well as patients with mental illness. However, there remains limited evidence supporting the treatment efficacy of AAT in middle-aged and older adults with schizophrenia. Therefore, this study implemented a randomized controlled trial to assess the efficacy of a 12-week AAT psychological intervention with dogs for middle-aged and older patients with chronic schizophrenia in a clinical setting. Method: Patients, age ≥ 40 years, with chronic schizophrenia were allocated randomly to either the AAT group or control group. Patients in the AAT group received an additional hour -long AAT session every week for 12 weeks. Patients in the control group received the usual treatment plus an hour long non-animal related intervention. All patients were assessed based on primary outcome measures before and after the 12-week intervention, including the Positive and Negative Syndrome Scale (PANSS), Depression Anxiety Stress Scales Assessment (DASS), and Chinese Happiness Inventory (CHI). Results: Patients who received AAT had greater improvements in the PANSS and DASS-stress subscale scores than the control group (p < 0.05). The effect was small (success ratio different, SRD = 0.25) for the PANSS and the DASS-stress subscale (SRD = 0.15). There were no significant differences in the change scores of the CHI between the AAT and control groups (p = 0.461). Conclusions: AAT seemed to be effective in reducing psychiatric symptoms and stress levels of middle-aged and older patients with schizophrenia. AAT could be considered as a useful adjunctive therapy to the usual treatment programs.
