We conducted a text message-based intervention for weight management over three months by two months intervention and one month wash-out period. In a quasi-experimental study with control (n = 40) and experimental group (n = 40), 80 overweight and obese employed women were entered. Participants were recruited via announcement. All subjects attended a face-to-face information session and received a booklet that contained food calorie chart and strategies and recommendations for weight management. The experimental group received text messages (SMS) about weight management twice a day for two months, in addition to the information and the booklet which they had received in the information session. Also, the experimental group was instructed to weekly self-weight and to send the data to the principle researcher. All subjects were measured for baseline and secondary weight in a standardized manner by a nurse, and the data were compared between the two groups. Experimental group lost more weight than the control group (1.5 kg difference, P = 0.018). Text messaging seems to be an effective channel of communication for weight management in Iranian overweight and obese women. The clinical trial registration number is IRCT201204029360N1.
Background Adherence to treatment is an important factor to decrease repeated and costly hospitalization owing to heart failure (HF). The explanation and prediction of medication adherence and other lifestyle recommendations in chronic diseases, including HF, are complex. Theories lead to a better understanding of complex situations as well as the process of changing behavior and explain the reasons for the existence of a problem. Objective The aim of this study is to report a protocol for a mixed methods study setting out to investigate the empirical validity of the Roy Adaptation Model as a conceptual framework for explaining and predicting adherence to treatment in patients with HF in Iran. Methods This mixed methods study consists of an exploratory sequential design to be conducted in 2 phases. The first phase involves identifying the factors associated with treatment adherence in patients with HF through content analysis of the literature and elucidating the perception of participants in the context of Iranian health care where the model of adherence to treatment is designed based on the Roy Adaptation Model. The second phase addresses the interrelationships among variables in the model through a descriptive study using structural equation modeling. Finally, following the summarization and separate interpretation of the qualitative findings and quantitative results, a decision is made about the extent to and ways in which the results of the quantitative stage can be generalized or tested for the qualitative findings. Results Content analysis of the literature in part 1 of the first phase was completed in 2017. Collection and analysis of qualitative data in part 2 of the first phase will be completed soon. The results are expected to be submitted for publication in 2019. Then, the second phase—the quantitative study—will be conducted. Conclusions The results of this study will provide valuable information about the empirical validity of the Roy Adaptation Model as a conceptual framework for explaining and predicting adherence to treatment in patients with HF, which, to date, have received little attention. The results can be used as a guide for nursing practice and care provision to patients with HF and also to design and implement effective interventions to improve treatment adherence in these patients.
