IntroductionAlthough being highly consensual that antipsychotic adherence is an important outcome predictor in psychosis, existing reviews have found mean rates of adherence around 40–60%. Several aspects, such as patient-related, medication-related, environmental-related variables have been described as important predictors.AimsThis study aim is to develop, administer and present preliminary psychometric properties of a new scale for antipsychotic medication adherence that includes different types of predictors (clinical, psychosocial, and practical among others).MethodsThe “AMAS” was developed by a multidisciplinary team and was based on recent research on factors influencing antipsychotic adherence. The scale evolved from multiple drafts and experts were contacted in order to improve the final version. Over 50 patients with a diagnosis of a psychotic-spectrum disorder taking antipsychotic medication will be assessed with the “AMAS” and the Medication Adherence Rating Scale. Additionally, each patient's psychiatrist will fill in a form with demographic and clinical variables (such as type of symptoms, previous adherence problems, current adherence, insight and other relevant variables).ResultsThis is an ongoing study and the sample is still being collected (scheduled finish date: February/2016). Our statistical analysis’ plan includes: reliability analysis (Chronbach's alpha, alpha if item deleted, inter item correlations and covariances and item-total correlations); validity (convergent validity); factorial analysis.ConclusionsIt is hypothesized that the “AMAS” will be a practical, reliable and valid unidimentional instrument with clinical utility assessing adherence to antipsychotics. The “AMAS” can be also useful in assessing intervention targets (e.g. psychoterapeutical, psychoeducational) to enhance adherence.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Issues in applied survey research, including minimizing respondent burden to encourage survey completion and the increasing administration of questionnaires over smartphones, have intensified efforts to create short measures. We conducted two studies to examine the psychometric properties of single-item measures of four close-relationship variables: satisfaction, love, conflict, and commitment. Study 1 was longitudinal, surveying an initial sample of 121 college-age dating couples at three monthly phases. Romantic partners completed single- and multi-item measures of the four constructs, along with other variables, to examine test-retest reliability and convergent (single-item measures with their corresponding multi-item scales), concurrent, and predictive validity. Our single-item measures of satisfaction, love, and commitment exhibited impressive psychometric qualities, but our single-item conflict measure performed somewhat less strongly. Study 2, a cross-sectional online survey (n = 280; mainly through Facebook), showed strong convergent validity of the single-item measures, including a .60 correlation between single- and multi-item conflict measures.

Abstract Background The Clinch Token Transfer Test (C3t) is a bi-manual coin transfer task that incorporates cognitive tasks to add complexity. This study explored the concurrent and convergent validity of the C3t as a simple, objective assessment of impairment that is reflective of disease severity in Huntington’s, that is not reliant on clinical expertise for administration. Methods One-hundred-and-five participants presenting with pre-manifest (n = 16) or manifest (TFC-Stage-1 n = 39; TFC-Stage-2 n = 43; TFC-Stage-3 n = 7) Huntington’s disease completed the Unified Huntington’s Disease Rating Scale and the C3t at baseline. Of these, thirty-three were followed up after 12 months. Regression was used to estimate baseline individual and composite clinical scores (including cognitive, motor, and functional ability) using baseline C3t scores. Correlations between C3t and clinical scores were assessed using Spearman’s R and visually inspected in relation to disease severity using scatterplots. Effect size over 12 months provided an indication of longitudinal behaviour of the C3t in relation to clinical measures. Results Baseline C3t scores predicted baseline clinical scores to within 9–13% accuracy, being associated with individual and composite clinical scores. Changes in C3t scores over 12 months were small ($$\Omega$$ Ω ≤ 0.15) and mirrored the change in clinical scores. Conclusion The C3t demonstrates promise as a simple, easy to administer, objective outcome measure capable of predicting impairment that is reflective of Huntington’s disease severity and offers a viable solution to support remote clinical monitoring. It may also offer utility as a screening tool for recruitment to clinical trials given preliminary indications of association with the prognostic index normed for Huntington’s disease.

Willingness To Forgive

PurposeThough brand love is recognized as being an important marketing topic both for theory and practice, a gap still exists with regard to its operationalization. To bridge this gap, this paper proposes a single-item measure (SIM) that uses a visual rating scale (i.e., a rating scale combining verbal with nonverbal contents).Design/methodology/approachThree studies covering over 700 respondents and examining three international brands over three product categories were conducted to test the new measure.FindingsFindings provide consistent evidence for the reliability and validity of the proposed measure. They also demonstrate that brand love, as gauged by the new SIM, is good in predicting positive word of mouth, willingness to pay a higher price, and willingness to forgive brand mishaps.Research limitations/implicationsThe paper focuses on brand love mainly from a measurement perspective.Practical implicationsThis paper provides a practical and parsimonious tool to measure brand love.Originality/valueExtant SIMs of brand love are less than ordinal, content invalid, of unknown reliability, and of untested concurrent validity. This paper provides academics and practitioners alike with a SIM of brand love that is ordinal, content valid, and tested in terms of reliability and concurrent validity.

Our study aimed to develop and provide a preliminary psychometric validation of theSomatomorphic Matrix-Female (SM-F), a new bidimensional female figural rating scale which can be used to gauge actual and desired levels of both body fat and muscularity in a consolidated measure, as well as providing an index of actual–desired body discrepancy based on these measures. Across two studies undergraduate women (n Study 1 = 481; n Study 2 = 391) completed the Eating Disorder Examination Questionnaire, the Body Shape Questionnaire-34, and the Depression Anxiety Stress Scales-21 (Study 1) and the Drive for Thinness Scale and the Drive for Muscularity Scale (Study 2), as well as the SM-F. Overall, the SM-F demonstrated sound content, concurrent, and convergent validity for actual and desired body fat, actual and desired muscularity, and their respective discrepancy scores

Rating Scale

Sekitar 42% dari 150 orang penderita gangguan bipolar di Indonesia mengeluhkan sulitnya mendapatkan obat yang biasa dikonsumsi saat pandemi Covid-19 dan kurangnya literasi kesehatan tentang obat yang memberikan efek yang sama dengan obat yang biasa mereka konsumsi sehingga tidak ada opsi lain jika orang dengan gangguan bipolar tidak mendapatkan obat.  Tujuan dari penelitian ini adalah untuk melihat gambaran kepatuhan minum obat pada penderita bipolar dimasa pandemi Covid-19. Metode penelitian ini adalah kuantitatif dengan menggunakan kuisioner Medication Adherence Rating Scale (MARS). Hasil dari indikator kepatuhan obat didapatkan sebanyak 12% memiliki sipak kepatuhn obat yang tinggi dan sebanyak 88% memiliki sipak kepatuhan obat yang rendah. Didapatkan juga sikap keputusan persepsi obat tinggi sebesar 4% dan sikap keputusan persepsi obat rendah sebesar 96%. Didapatkan data persepsi efek samping obat rendah sebesar 100%. Hal ini menunjukkan rendahnya kepatuhan obat pada penderita gangguan bipolar dimasa pandemic Covid-19 ini
