The Diabetes Self-Management Questionnaire (DSMQ): development and evaluation of an instrument to assess diabetes self-care activities associated with glycaemic control.

BackgroundThough several questionnaires on self-care and regimen adherence have been introduced, the evaluations do not always report consistent and substantial correlations with measures of glycaemic control. Small ability to explain variance in HbA1c constitutes a significant limitation of an instrument’s use for scientific purposes as well as clinical practice. In order to assess self-care activities which can predict glycaemic control, the Diabetes Self-Management Questionnaire (DSMQ) was designed.MethodsA 16 item questionnaire to assess self-care activities associated with glycaemic control was developed, based on theoretical considerations and a process of empirical improvements. Four subscales, ‘Glucose Management’ (GM), ‘Dietary Control’ (DC), ‘Physical Activity’ (PA), and ‘Health-Care Use’ (HU), as well as a ‘Sum Scale’ (SS) as a global measure of self-care were derived. To evaluate its psychometric quality, 261 patients with type 1 or 2 diabetes were assessed with the DSMQ and an established analogous scale, the Summary of Diabetes Self-Care Activities Measure (SDSCA). The DSMQ’s item and scale characteristics as well as factorial and convergent validity were analysed, and its convergence with HbA1c was compared to the SDSCA.ResultsThe items showed appropriate characteristics (mean item-total-correlation: 0.46 ± 0.12; mean correlation with HbA1c: -0.23 ± 0.09). Overall internal consistency (Cronbach’s alpha) was good (0.84), consistencies of the subscales were acceptable (GM: 0.77; DC: 0.77; PA: 0.76; HU: 0.60). Principal component analysis indicated a four factor structure and confirmed the designed scale structure. Confirmatory factor analysis indicated appropriate fit of the four factor model. The DSMQ scales showed significant convergent correlations with their parallel SDSCA scales (GM: 0.57; DC: 0.52; PA: 0.58; HU: n/a; SS: 0.57) and HbA1c (GM: -0.39; DC: -0.30; PA: -0.15; HU: -0.22; SS: -0.40). All correlations with HbA1c were significantly stronger than those obtained with the SDSCA.ConclusionsThis study provides preliminary evidence that the DSMQ is a reliable and valid instrument and enables an efficient assessment of self-care behaviours associated with glycaemic control. The questionnaire should be valuable for scientific analyses as well as clinical use in both type 1 and type 2 diabetes patients.

Breakfast habits, beliefs and measures of health and wellbeing in a nationally representative UK sample

The aim of this study was to report UK adult breakfasting habits, beliefs and the relationship of both with measures of personality, health and wellbeing including physical activity and body mass index (BMI). A nationally representative sample of 1068 adults completed a web-based survey, combining standardised scales and self-designed questionnaire statements. Sixty-four percent of respondents consumed breakfast daily whilst 6% never ate breakfast. Breakfasting frequency was found to correlate with conscientiousness, wellbeing and age and general health. The survey found that breakfast eaters strongly believe that breakfast helps weight control and weight loss. Breakfast eaters were more likely to partake in vigorous exercise, although there was no significant difference in BMI. Multi-variate analysis identified conscientiousness, cognitive restraint and age as making unique contributions to predicting breakfast frequency. This study provides further support for the view that breakfast eating is likely to be a proxy-variable for a healthy lifestyle. The role of breakfast and related beliefs should be taken into consideration in breakfast behaviour research, interventions and health and wellbeing campaigns.

Experimental manipulation of breakfast in normal and overweight/obese participants is associated with changes to nutrient and energy intake consumption patterns

The effect of breakfast and breakfast omission on daily food intake in normal and overweight participants was investigated. 37 participants were recruited for this experimental study and assigned to one of four groups on the basis of their body mass index (BMI) (normal weight BMI <25 kg/m(2) or overweight/obese BMI >25 kg/m(2)) and breakfast habits (breakfast eater or breakfast omitter). All participants were requested to eat breakfast for an entire week, and then following a washout period, omit breakfast for an entire week, or vice versa. Seven-day food diaries reporting what was consumed and the timing of consumption were completed for each breakfast condition. Overall more energy was consumed during the breakfast than the no breakfast week. The present study revealed significant effects of timing on energy intakes; more energy was consumed during the afternoon in the no breakfast week compared to the breakfast week. Overweight participants consumed greater amounts of energy than normal weight participants in the early evening. Breakfast omitters consumed more than did breakfast eaters later in the evening. All groups consumed significantly less energy, carbohydrate and fibre in the no breakfast week; however, overweight participants increased their sugar intakes. Consumption of the micronutrients iron and folate was reduced in the no breakfast week. The findings highlight that the timing of food intake and habitual breakfast eating behaviour are important factors when investigating why breakfast consumption may be associated with BMI.

A Methodology to Analyze the Quality of Health Information on the Internet: The Example of Diabetic Neuropathy

Purpose The purpose of this work was to evaluate the criteria used to assess the quality of information on diabetic neuropathy on the Internet. Methods Different search engines (Google, Yahoo, Bing, and Ask) and 1 governmental health website (MedlinePlus) were studied. The websites returned (200 for each search engine) were then classified according to their affiliation (eg, commercial, professional, patient groups). A scoring system was devised from the literature to assess quality of information. Websites were also analyzed using the 2 most widely used instruments for assessing the quality of health information, the Journal of the American Medical Association (JAMA) scoring system and the Health On the Net Foundation (HON) certification. Results Professional websites or health portals scored better according to most criteria. Google and MedlinePlus returned results scoring significantly higher than other engines in some of the criteria. The use of different instruments gave different results and indicates that the JAMA score and the HON certification may not be sufficient ones. Conclusions This methodology could be used to evaluate the reliability and trustworthiness of information on the Internet on different topics to identify topic areas or websites where the available information is not appropriate.

Depression is linked to hyperglycaemia via suboptimal diabetes self-management: A cross-sectional mediation analysis

OBJECTIVE To analyse if the association between depressive symptoms and hyperglycaemia is mediated by diabetes self-management. METHODS 430 people with diabetes (57.7% type 1, 42.3% type 2) were cross-sectionally assessed using validated self-report scales for depressive symptoms (Center for Epidemiologic Studies Depression Scale (CES-D)) and diabetes self-management (Diabetes Self-Management Questionnaire (DSMQ)); HbA1c was analysed simultaneously in a central laboratory. Structural equation modelling was used to test if the association between depressive symptoms and hyperglycaemia (HbA1c) was mediated by suboptimal self-management in people with type 1 and type 2 diabetes. RESULTS The hypothesised model of depressive symptoms, diabetes self-management and hyperglycaemia fit the data well for both diabetes types (SRMR≤0.04, TLI≥0.99, CFI>0.99, RMSEA≤0.02 for both models). In both the type 1 and type 2 diabetes group, higher depressive symptoms were associated with lower self-management (P<0.001) and lower self-management was associated with higher HbA1c (P<0.001). Results indicated that the association between depressive symptoms and hyperglycaemia was significantly mediated by suboptimal diabetes self-management in both type 1 and type 2 diabetes patients (P<0.001). Significant direct associations between depressive symptoms and hyperglycaemia, not mediated by self-management, could not be observed. CONCLUSIONS This study provides good evidence supporting that depression is linked to hyperglycaemia via suboptimal diabetes self-management in both major diabetes types.

A cross-over experiment to investigate possible mechanisms for lower BMIs in people who habitually eat breakfast

Background/Objectives:The body mass index (BMI) of breakfast eaters is frequently reported to be lower compared with that of breakfast skippers. This is not explained by differences in energy intakes, indicating there may be other mechanisms serving to drive this paradoxical association between breakfast and BMI. This study aimed to investigate the effect of eating breakfast versus morning fasting on measures predominantly of metabolism in lean and overweight participants who habitually eat or skip breakfast.Subjects/Methods:Participants (n=37) were recruited into four groups on the basis of BMI (lean and overweight) and breakfast habit (breakfast eater and breakfast skipper). Participants were randomly assigned to a breakfast experimental condition, breakfast eating or no breakfast, for 7 days and then completed the alternative condition. At the end of each breakfast experimental condition, measurements were made before and after a high carbohydrate breakfast of 2274±777 kJ or a rest period. Resting metabolic rate, thermic effect of food (TEF), blood glucose, insulin and leptin levels were recorded. Hunger and ‘morningness’ were assessed and pedometers worn.Results:Lean participants had lower fasting insulin levels (P=0.045) and higher insulin concentrations following breakfast (P=0.001). BMI and breakfast habit did not interact with the experimental breakfast condition, with the exception of hunger ratings; breakfast eaters were hungrier in the mornings compared with breakfast skippers in the no breakfast condition (P=0.001).Conclusions:There is little evidence from this study for a metabolic-based mechanism to explain lower BMIs in breakfast eaters.

Implementing the National Service Framework for Long-Term (Neurological) Conditions: service user and service provider experiences.

Abstract Purpose: This research explored the experiences of service users and providers during the implementation of the National Service Framework (NSF) for Long-Term (Neurological) Conditions (LTNCs). Method: A participatory qualitative research design was employed. Data were collected using 50 semi-structured interviews with service users, 25 of whom were re-interviewed on three occasions. Forty-five semi-structured interviews were also conducted with service providers who worked with individuals with LTNCs. Interviews focused on health, well-being and quality of life in relation to service provision, access and delivery. Data were thematically analysed individually and collaboratively during two data analysis workshops. Results: Three major themes were identified that related to the implementation of the NSF: “Diagnosis and treatment”, “Better connected services” and “On-going rehabilitation”. Service users reported that effective care was provided when in hospital settings but such treatments often terminated on return to their communities despite on-going need. In hospital and community settings, service providers indicated that they lacked the support and resources to provide continuous care, with patients reaching a crisis point before referral to specialist care. Conclusion: This research highlighted a range of issues concerning the recent UK-drive towards patient-centred approaches within healthcare, as service users were disempowered within the LTNC care pathway. Moreover, service providers indicated that resource constraints limited their ability to provide long-term, intensive and integrated service provision. Implications for Rehabilitation Our research suggests that many service users with long-term neurological conditions experienced disconnections between services within their National Service Framework care pathway. For health and social care practitioners, a lack of continuity within a care pathway was suggested to be most pertinent following immediate care and moving to rehabilitative care. Our findings also indicate that service providers lack the necessary financial resources and staffing capacity to provide on-going and comprehensive rehabilitation. This article aims to help practitioners better understand particular issues during the implementation of the National Service Framework for long-term neurological conditions from the perspectives of service users and service providers.

Assessing Diabetes Self-Management with the Diabetes Self-Management Questionnaire (DSMQ) Can Help Analyse Behavioural Problems Related to Reduced Glycaemic Control

Aim To appraise the Diabetes Self-Management Questionnaire (DSMQ)’s measurement of diabetes self-management as a statistical predictor of glycaemic control relative to the widely used SDSCA. Methods 248 patients with type 1 diabetes and 182 patients with type 2 diabetes were cross-sectionally assessed using the two self-report measures of diabetes self-management DSMQ and SDSCA; the scales were used as competing predictors of HbA1c. We developed a structural equation model of self-management as measured by the DSMQ and analysed the amount of variation explained in HbA1c; an analogue model was developed for the SDSCA. Results The structural equation models of self-management and glycaemic control showed very good fit to the data. The DSMQ’s measurement of self-management showed associations with HbA1c of –0.53 for type 1 and –0.46 for type 2 diabetes (both P < 0.001), explaining 21% and 28% of variation in glycaemic control, respectively. The SDSCA’s measurement showed associations with HbA1c of –0.14 (P = 0.030) for type 1 and –0.31 (P = 0.003) for type 2 diabetes, explaining 2% and 10% of glycaemic variation. Predictive power for glycaemic control was significantly higher for the DSMQ (P < 0.001). Conclusions This study supports the DSMQ as the preferred tool when analysing self-reported behavioural problems related to reduced glycaemic control. The scale may be useful for clinical assessments of patients with suboptimal diabetes outcomes or research on factors affecting associations between self-management behaviours and glycaemic control.

Care planning for aggression management in a specialist secure mental health service: An audit of user involvement

This paper describes an audit of prevention and management of violence and aggression care plans and incident reporting forms which aimed to: (i) report the compliance rate of completion of care plans; (ii) identify the extent to which patients contribute to and agree with their care plan; (iii) describe de-escalation methods documented in care plans; and (iv) ascertain the extent to which the de-escalation methods described in the care plan are recorded as having been attempted in the event of an incident. Care plans and incident report forms were examined for all patients in mens and womens mental health care pathways who were involved in aggressive incidents between May and October 2012. In total, 539 incidents were examined, involving 147 patients and 121 care plans. There was no care plan in place at the time of 151 incidents giving a compliance rate of 72%. It was documented that 40% of patients had contributed to their care plans. Thematic analysis of de-escalation methods documented in the care plans revealed five de-escalation themes: staff interventions, interactions, space/quiet, activities and patient strategies/skills. A sixth category, coercive strategies, was also documented. Evidence of adherence to de-escalation elements of the care plan was documented in 58% of incidents. The reasons for the low compliance rate and very low documentation of patient involvement need further investigation. The inclusion of coercive strategies within de-escalation documentation suggests that some staff fundamentally misunderstand de-escalation.
