Development,validity and reliability of the short multidimensional positive mental health instrument

Purpose

The 47-item positive mental health (PMH) instrument measures the level of PMH in multiethnic adult Asian populations. This study aimed to (1) develop a short PMH instrument and (2) establish its validity and reliability among the adult Singapore population.

Methods

Two separate studies were conducted among adult community-dwelling Singapore residents of Chinese, Malay or Indian ethnicity where participants completed self-administered questionnaires. In the first study, secondary data analysis was conducted using confirmatory factor analysis (CFA) to shorten the PMH instrument. In the second study, the newly developed short PMH instrument and other scales were administered to 201 residents to establish its factor structure, validity and reliability.

Results

A 20-item short PMH instrument fulfilling a higher-order six-factor structure was developed following secondary analysis. The mean age of the participants in the second study was 41 years and about 53 % were women. One item with poor factor loading was further removed to generate a 19-item version of the PMH instrument. CFA demonstrated a first-order six-factor model of the short PMH instrument. The PMH-19 instrument and its subscales fulfilled criterion validity hypotheses. Internal consistency and test–retest reliability of the PMH-19 instrument were high (Cronbach’s α coefficient = 0.87; intraclass correlation coefficient = 0.93, respectively).

Conclusions

The 19-item PMH instrument is multidimensional, valid and reliable, and most importantly, with its reduced administration time, the short PMH instrument can be used to measure and evaluate PMH in Asian communities.

The water balance questionnaire: design, reliability and validity of a questionnaire to evaluate water balance in the general population

There is a need to develop a questionnaire as a research tool for the evaluation of water balance in the general population. The water balance questionnaire (WBQ) was designed to evaluate water intake from fluid and solid foods and drinking water, and water loss from urine, faeces and sweat at sedentary conditions and physical activity. For validation purposes, the WBQ was administrated in 40 apparently healthy participants aged 22-57 years (37.5% males). Hydration indices in urine (24 h volume, osmolality, specific gravity, pH, colour) were measured through established procedures. Furthermore, the questionnaire was administered twice to 175 subjects to evaluate its reliability. Kendall's τ-b and the Bland and Altman method were used to assess the questionnaire's validity and reliability. The proposed WBQ to assess water balance in healthy individuals was found to be valid and reliable, and it could thus be a useful tool in future projects that aim to evaluate water balance.

Patient satisfaction, feasibility and reliability of satisfaction questionnaire among patients with pulmonary tuberculosis in urban Uganda: a cross-sectional study

Background

A comprehensive understanding of the barriers to and facilitators of poor tuberculosis (TB) treatment outcome is still lacking; posing a major obstacle to finding effective solutions. Assessment of patient satisfaction in TB programs would contribute to the understanding of gaps in healthcare delivery and the specific needs of individual patients. However, tools for assessing patient satisfaction are lacking.

Objective

To establish patient satisfaction, the feasibility and reliability of a questionnaire for healthcare service satisfaction and a questionnaire for satisfaction with information received about TB medicines among adult TB patients attending public and private program clinics in Kampala, Uganda.

Methods

In a cross-sectional study, we recruited 133 patients of known HIV status and confirmed pulmonary TB receiving care at the public and private hospitals in Kampala, Uganda. Participants were enrolled based on length of TB treatment as follows: starting therapy, completed two months of therapy, and completed eight months of therapy. A translated and standardized 13-item patient healthcare service satisfaction questionnaire (PS-13) and the Satisfaction with Information about Medicines Scale (SIMS) tool were administered by trained interviewers. Factor analysis was used to systematically group the PS-13 questionnaire into three factors of technical quality of care, responsiveness to patient preference, and management of patient preference satisfaction subscales. The SIMS tool was analyzed with two subscales of information about the action and usage of medication and the potential problems with medication.

Results

Of the 133 participants, 35% (46/133) were starting, 33% (44/133) had completed two months, and 32% (43/133) had completed eight months of TB therapy. The male to female and public to private hospital ratios in the study population were 1:1. The PS-13 and the SIMS tools were highly acceptable and easily administered. Both scales and the subscales demonstrated acceptable internal consistency with Cronbach's alpha above 0.70. Patients that were enrolled at the public hospital had relatively lower PS-13 satisfaction scores (0.48 (95% confidence interval (CI), 0.42 - 0.52)), (0.86 (95% CI, 0.81 - 0.90)) for technical quality of care and responsiveness to patient preferences, respectively compared to patients that were enrolled at the private hospital. For potential problems SIMS subscale, male patients that were recruited at the public hospital had relatively lower satisfaction scores (0.58 (95% CI, 0.40 - 0.86)) compared to female patients after adjusting for other factors. Similarly, patients that had completed eight months of TB treatment had relatively higher satisfaction scores (1.23 (95% CI, 1.06 - 1.44)) for action and usage SIMS subscale, and higher satisfaction scores (1.09 (95% CI, 1.03 - 1.16)) for management of patient preference (PS-13 satisfaction subscale) compared to patients that were starting treatment, respectively.

Conclusion

The study provides preliminary evidence that the PS-13 service satisfaction and the SIMS tools are reliable measures of patient satisfaction in TB programs. Satisfaction score findings suggest differences in patient satisfaction levels between public and private hospitals; between patients starting and those completing TB therapy.     

Comparison of three visit-specific patient satisfaction instruments: reliability and validity measures and the effect of four methods of data collection on dimensions of patient satisfaction

The purposes of this study were to evaluate the reliability and validity of three short-form patient satisfaction instruments and to examine the effects of data collection methods on patient satisfaction ratings. With a framework to assess quality of care from the patient's perspective, acceptability, accessibility, patient satisfaction rating, provider recommendation, and patient demographic data were collected using three patient surveys: the Health Outcomes Institute questionnaire (HOI); the Nalle Clinic survey (Nalle); and a commercially marketed survey (COM). The four methods of data collection were (1) receptionist-distributed at check-in, (2) student-distributed at check-out, (3) mail, and (4) phone. Data were collected on a systematically selected sample of 1,840 patients who were appointed in two family practice departments of the Nalle Clinic in Charlotte, North Carolina. From the 925 completed surveys, the results indicated that the HOI instrument scored higher on the reliability and validity measures in this patient sample than the Nalle or COM surveys. Analysis of variance was then conducted on the HOI scores across the four methods of data collection. The conclusion was that the method of data collection did not significantly influence any of the patient satisfaction indicators in the family practice sample.     

Development of a French inpatient satisfaction questionnaire.

OBJECTIVE: To develop a brief French-language, generic, self-administered questionnaire to measure inpatient satisfaction. DESIGN: Issues relevant to patients were identified using three open-ended questions designed in accordance with the disconfirmation paradigm. The content of patients' responses was analysed and then supplemented by items taken from published instruments in order to generate a pool of 93 items. Twenty-nine items were selected following a strict procedure. Content validity was judged by comparing the questionnaire to existing instruments. Construct validity was supported by testing specific hypotheses derived from the literature and by performing principal component analysis. Reliability was estimated by calculating Cronbach's alpha. SETTING: A 2200-bed French teaching hospital. SUBJECTS: A mail survey was carried out on a random sample of 1000 inpatients within 2-4 weeks of discharge. Eligible subjects were medical, surgical and obstetrics inpatients who had stayed in the hospital for more than 24 hours. RESULTS: The participation rate (71%) and the completion rate (95%) were indicators of acceptability. There were modest differences between the questionnaire and published instruments (financial aspects, amenities). Construct representation by principal component analysis consisted of six scales which accounted for 58% of the variance in total satisfaction scores. The reliability estimates of internal consistency ranged from 0.67 to 0.86. CONCLUSION: We propose that the self-administered multidimensional inpatient satisfaction questionnaire provided encouraging preliminary psychometric information. This instrument is intended to involve patient feedback in a continuous quality health care improvement strategy.     

Development and validation of a multidimensional questionnaire assessing non-adherence to medicines

The study aimed to develop and validate an instrument capable of measuring non-adherence to drug treatment in its multiple dimensions. The Questionário de Ades?o a Medicamentos (Adherence to Medicines Questionnaire) with three questions was applied to 46 people with arterial hypertension in the city of Blumenau, Southern Brazil, in 2006. Non-adherence measures obtained were compared to four other methods (Haynes, Morisky, pill count and clinical outcome). Non-adherence measures varied according to the method. The combined Questionário de Ades?o a Medicamentos non-adherence measure was 47.8% (95% CI: 32.9;63.1), whereas the gold standard was 69.6% (95% CI: 54.3;82.3). Accuracy measures to detect non-adherence showed a sensitivity of 62.5% and specificity of 85.7%, ROC curve area of 74.1%, and positive predictive value of 90.9%. Results suggest the Questionário de Ades?o a Medicamentos has a good fit.
