The reporting of cluster analysis was found to be generally unsatisfactory, with many studies failing to provide enough information to allow replication or the evaluation of the quality of the research. Clear guidelines for conducting and reporting cluster analyses in health psychology are needed.

Background: Cardiovascular events are the leading cause of death in end stage renal disease (ESRD). Adherence to phosphate binding medication plays a vital role in reducing serum phosphorus and associated cardiovascular risk. This poses a challenge for patients as the regimen is often complex and there may be no noticeable impact of adherence on symptoms. There is a need to establish the level of nonadherence to phosphate binding medication in renal dialysis patients and identify the factors associated with it.

This is the largest review of factors associated with non-adherence in IBD. Demographic, clinical, and treatment variables were not consistently associated with non-adherence. Psychological distress, patients' beliefs about medications, and doctor-patient discordance were associated with non-adherence. These findings call into question some of the conclusions of earlier reviews that did not take into account nonsignificant findings. Practical suggestions for gastroenterologists and future research are discussed.

AimA systematic review of reviews was conducted to identify and appraise brief measures of health-related quality of life (HRQoL) that have been used in peer-reviewed research with people living with HIV.MethodsThe review was conducted in two stages: 1) search of electronic databases to identify systematic reviews of tools used to measure HRQoL in adults living with HIV, published since the year 2000; 2) selection of HRQol scales from those identified in the reviews. Inclusion criteria included scales that could be self-administered in 10 min or less, covering at least 3 domains of quality of life (physical function, social/role function and mental/emotional function). For generic scales, inclusion criteria included the availability of normative data while for HIV-specific scales, patient input into the development of the scale was required.ResultsTen reviews met the inclusion criteria. Nine generic scales met the inclusion criteria: the EuroQol five dimensions questionnaire (EQ-5D); Health Utilities Index; McGill Quality of Life questionnaire; Medical Outcomes Study (MOS) Short Form (SF)-12; SF-36; World Health Organisation Quality of Life (WHOQOL- BREF), Questions of Life Satisfaction (FLZM) and SF-20. Available psychometric data supported the EQ-5D and SF-36. Seven HIV-specific scales met the inclusion criteria: the AIDS Clinical Trials Group (ACTG)-21; HIV-QL-31; MOS-HIV; Multidimensional Quality of Life Questionnaire for Persons with HIV/AIDS (MQOL-HIV), PROQOL-HIV, Symptom Quality of Life Adherence (HIV-SQUAD) and the WHOQOL-HIV BREF. Of the HIV -specific measures, the MOS-HIV was considered to have the most well-established psychometric properties, however limitations identified in the reviews included insufficient input from people living with HIV in the development of the scale, cross-cultural relevance and continued applicability. Two relatively new measures, the WHOQOL-HIV BREF and PROQOL-HIV, were considered to have promising psychometric properties and may have more relevance to people living with HIV.ConclusionThe findings highlight the need for further validation of HRQoL measures in people living with HIV. The choice of one measure over another is likely to be influenced by the purpose of the quality of life assessment and the domains of HRQoL that are most relevant to the specific research or clinical question.

Aims: To explore the utility of self-report measures of inhaled corticosteroid (ICS) adherence, degree of rhinitis and smoking status and their association with asthma control.Methods: Patients prescribed ICS for asthma at 85 UK practices were sent validated questionnaire measures of control (Asthma Control Questionnaire; ACQ) and adherence (Medication Adherence Report Scale), a two-item measure of smoking status, and a single-item measure of rhinitis.Results: Complete anonymised questionnaires were available for 3916 participants. Poor asthma control (ACQ >1.5) was associated with reported rhinitis (OR = 4.62; 95% CI: 3.71-5.77), smoking (OR = 4.33; 95% CI: 3.58-5.23) and low adherence to ICS (OR = 1.35; 95% CI: 1.18-1.55). The degree of rhinitis was important, with those reporting severe rhinitis exhibiting the worst asthma control, followed by those reporting mild rhinitis and then those reporting no rhinitis symptoms (F(2, 3913)=128.7, p<.001). There was a relationship between the number of cigarettes smoked each day and asthma control (F(5,655)=6.08, p<.001).Conclusions: Poor asthma control is associated with self-reported rhinitis, smoking and low medication adherence. These potentially modifiable predictors of poor asthma control can be identified through a brief self-report questionnaire, used routinely as part of an asthma review.

Purpose -The number of gardening-based mental health interventions is increasing, yet when the literature was last reviewed in 2003, limited evidence of their effectiveness was identified. The purpose of this paper is to evaluate the current evidence-base for gardening-based mental health interventions and projects through examining their reported benefits and the quality of research in this field. Design/methodology/approach -Studies evaluating the benefits of gardening-based interventions for adults experiencing mental health difficulties were identified through an electronic database search. Information on the content and theoretical foundations of the interventions, the identified benefits of the interventions and the study methodology was extracted and synthesised. Findings -Ten papers published since 2003 met the inclusion criteria. All reported positive effects of gardening as a mental health intervention for service users, including reduced symptoms of depression and anxiety. Participants described a range of benefits across emotional, social, vocational, physical and spiritual domains. Overall the research was of a considerably higher quality than that reviewed in 2003, providing more convincing evidence in support of gardening-based interventions. However, none of the studies employed a randomised-controlled trial design. Research limitations/implications -There is a need for further high-quality research in this field. It is important that adequate outcome measures are in place to evaluate existing gardening-based mental health interventions/projects effectively. Originality/value -This paper provides an up-to-date critique of the evidence for gardening-based mental health interventions, highlighting their potential clinical value.

Background:Self-management is an important aspect of long-term HIV treatment. Mobile technologies offer the potential to efficiently deliver interventions to facilitate HIV self-management. The last comprehensive review of such mHealth interventions was conducted in 2011. Given the rapidly evolving field, a need was identified for an updated review of the literature.Objective:The study aimed to describe and evaluate current evidence-based mHealth interventions to support self-management in HIV.Method:Eight online databases (Medline, Scopus, Embase, PsycINFO, Cochrane, Global Health CAB, IEEE explore, Web of Science) were systematically searched for papers describing and evaluating mHealth HIV self-management interventions. Reference lists of relevant papers were also searched. Data on intervention content and evaluation methodology were extracted and appraised by two researchers.Results:41 papers were identified evaluating 28 interventions. The majority of these interventions (n=20, 71%) had a single focus of either improving adherence (n=16), increasing engagement in care (n=3) or supporting smoking cessation (n=1), while just 8 (29%) were more complex self-management interventions, targeting a range of health-related behaviours. Interventions were predominantly delivered through SMS messaging. They significantly impacted on a range of outcomes including adherence, viral load, mental health and social support.Conclusion:Since the last major review of mHealth interventions in HIV, there has been a shift from exploratory acceptability/feasibility studies to impact evaluations. While overall the interventions impacted on a range of outcomes, they were generally limited in scope, failing to encompass many functions identified as desirable by people living with HIV. Participant incentives may limit the generalizability of findings.
