- Osteoarthritis (OA) is a common chronic disorder among elderly people that affects joints such as the knee and hip in particular. The objective of the current study was to examine the efficacy of an intervention based on a theory of planned behavior (TPB) in improving health-related quality of life in middle-age and older adults with this condition. One hundred twenty patients diagnosed with knee/hip OA were recruited from a general hospital. Measures administered at baseline were the SF-12, EuroQol (EQ-5D), Osteoarthritis Knee and Hip Quality of Life (OAKHQoL), and TPB questionnaire. Also assessed were body mass index (BMI), Kellgren-Lawrence Scale, six-minute walk test (SMWT), muscle strength, range of motion (ROM), and joint tenderness and swelling. Participants were randomly assigned to either the intervention (n = 60) or the control group (n = 60). The intervention group received an educational program based on TPB that was administered over 1 month. The control group did not receive this treatment. Three months after the intervention, both groups were reevaluated and comparisons made. Compared to the no-treatment control group, those in the intervention group scored higher on HRQoL, both general and specific, at 3-month follow-up (p < 0.01). The only exception was the vitality domain. Significant differences were also found on the TPB questionnaire, the SMWT, and muscle strength in the expected direction (p < 0.05). While those in the intervention group improved significantly on all clinical measures from pre-test to post-test, those in the control group showed improvement only on BMI and joint tenderness. This TPB-based intervention was found to be efficacious in improving HRQoL and several clinical parameters in patients with knee/hip OA. Studies are needed to examine the effectiveness of this intervention in patients with other chronic medical conditions.

- BACKGROUND: Nosocomial infection (NI) is common in health care settings. Educational strategies such as mobile teaching methods for health care providers may help to resolve this problem. This pilot study assessed the influence of a text messaging program to improve intensive care unit nurses' knowledge, attitude, and practice related to NI prevention.METHOD: In this single-group experimental study, 32 nurses received an educational intervention via short text messages on their cell phones. Information on knowledge, attitude, and practice regarding NI prevention was collected using a standard scale. Preventive messages about NI were prepared and sent to participants during a 2-month trial. Results were assessed 2 weeks after the intervention, and data were analyzed by paired t test.RESULTS: Knowledge, attitude, and practice of participants increased by 17%, 3%, and 9%, respectively, from baseline to follow up. The average score on the knowledge dimension was lower than for other components. Knowledge components such as hand hygiene, work safety, and protective equipment increased to a lesser degree from pre- to posttest, compared with other aspects (p < .05 versus p < .001).CONCLUSION: An education-based program operating through short text messages may be a useful in-service training strategy for intensive care unit nurses.

- Health-related quality of life (HRQoL) among patients with diabetes mellitus is often poorer than in those with other chronic medical conditions. Appropriate disease specific measures are needed to measure HRQoL in these patients. This study sought to validate a culturally adapted version of the Diabetes-Mellitus Specific Quality of Life (DMQoL) questionnaire module in Persian. Concurrent validity of the scale was assessed by the Diabetes Quality of Life (DQOL) questionnaire. Convergent and discriminative validity of the DMQoL was determined using a brief version of World Health Organization’s Quality of Life Scale Brief version (WHOQOL-BREF), Hospital Anxiety and Depression Scales (HADS), and Medication Adherence Report Scale (MARS). Construct validity was examined using confirmatory factor analysis. Rasch analysis was also performed to examine the unidimensionality of the DMQoL. Known-group method was used to examine the ability of the scale to differentiate between different categories of patients. A sample of 824 patients (512 females) with diabetes mellitus was recruited from diabetic care centers located in Qazvin, Iran. The mean age of participants was 54.1 (SD 6.3) and 27% were smokers. All items loaded on a single factor (factor loadings ≥ 0.6) and internal consistency of the scale was acceptable (α = 0.89). Significant associations were found between the scale and DQOL, indicating concurrent validity (p < 0.001). The DMQoL was able to differentiate subgroups of patients with hypertension, HbA1c, cholesterol, and diabetic diet. All items were appropriate with regard to difficulty level and confirmatory factor analysis verified the scale’s single dimension (CFI = 0.927; RMSEA = 0.067). Persian DMQoL is a reliable and valid measure of HRQoL in a Persian-speaking population with type II diabetes. Further assessment is needed to confirm the psychometric properties of the scale in other cultures and languages. Future studies are needed to determine the sensitivity of the scale to change over time in response to treatment.

- Background: Designing a health promotion program to increase physical activity may contribute to weight management. The purpose of this study was to investigate a theory of planned behavior (TPB) program to address this problem in military people.Methods: Eighty-four obese/overweight military personnel were randomised into the intervention or control group. A questionnaire assessed demographics, aspects of the TPB program, and physical activity levels. Also assessed were blood glucose and lipid levels. The intervention consisted of seven educational sessions based on TPB. Data were collected at baseline and 3 months after the intervention.Results: All constructs of the TPB improved between baseline and follow-up in the intervention group (p <.001), while there were no significant changes in the control group (within-group comparisons). Between-group comparisons on TPB measures revealed differences in all domains when results were controlled for baseline covariates. Greater light and moderate physical activity was observed in the intervention group. Body mass index decreased significantly within the intervention group (p <.001). Changes in triglyceride and high-density lipoprotein also favored the intervention over the control group.Conclusion: An intervention based on the TPB may be effective in promoting physical activity and decreasing weight in military personnel who are obese or overweight.
