Practice Links was created to enable practitioners to keep up-to-date with new publications, electronic resources and conference opportunities. Issue 50 celebrates the tenth anniversary of the original publication of Practice Links in 2002. In addition to this milestone the issue features reviews on Behavioural and Cognitive-Behavioural Group-Based Parenting Programmes for Early-Onset Conduct Problems in Children Aged 3 to 12 Years.

Research into the potential of short interventions in promoting well-being among adolescents

The present research examines the issue of universal interventions designed to enhance wellbeing among a community-based adolescent population. The first phase saw a cross-sectional survey conducted among Transition Year students in 13 secondary schools in Cork city and county, Republic of Ireland, with a view towards identifying dimensions linked with wellbeing (operationalised as subjective happiness, life satisfaction, and depressive symptoms) and which might prove effective in informing intervention approaches. Arising from this, mindfulness, gratitude, and cognitive-behavioural dimensions emerged as predictors of wellbeing, and short interventions (four sessions/four weeks) informed by each were conducted with participant groups in three secondary schools, one intervention in each school. Results from statistical analysis showed that the mindfulness and cognitive-behavioural interventions facilitated significant reductions in depressive symptoms among active condition participants at post-test, but that these benefits were not sustained over time, while no statistically significant changes were detected on subjective happiness and life satisfaction. The gratitude intervention was found to have had no effect on the three outcome variables. The findings are discussed in the context of theory and past research, while limitations, implications, and possible future directions are also addressed.

Identifying novel molecular mechanisms of ghrelin receptor signalling underlying neural control of food intake: interaction with stress and impulsivity

The gut-hormone, ghrelin, activates the centrally expressed growth hormone secretagogue 1a (GHS-R1a) receptor, or ghrelin receptor. The ghrelin receptor is a G-protein coupled receptor (GPCR) expressed in several brain regions, including the arcuate nucleus (Arc), lateral hypothalamus (LH), ventral tegmental area (VTA), nucleus accumbens (NAcc) and amygdala. Activation of the GHS-R1a mediates a multitude of biological activities, including release of growth hormone and food intake. The ghrelin signalling system also plays a key role in the hedonic aspects of food intake and activates the dopaminergic mesolimbic circuit involved in reward signalling. Recently, ghrelin has been shown to be involved in mediating a stress response and to mediate stress-induced food reward behaviour via its interaction with the HPA-axis at the level of the anterior pituitary. Here, we focus on the role of the GHS-R1a receptor in reward behaviour, including the motivation to eat, its anxiogenic effects, and its role in impulsive behaviour. We investigate the functional selectivity and pharmacology of GHS-R1a receptor ligands as well as crosstalk of the GHS-R1a receptor with the serotonin 2C (5-HT2C) receptor, which represent another major target in the regulation of eating behaviour, stress-sensitivity and impulse control disorders. We demonstrate, to our knowledge for the first time, the direct impact of GHS-R1a signalling on impulsive responding in a 2-choice serial reaction time task (2CSRTT) and show a role for the 5-HT2C receptor in modulating amphetamine-associated impulsive action. Finally, we investigate differential gene expression patterns in the mesocorticolimbic pathway, specifically in the NAcc and PFC, between innate low- and high-impulsive rats. Together, these findings are poised to have important implications in the development of novel treatment strategies to combat eating disorders, including obesity and binge eating disorders as well as impulse control disorders, including, substance abuse and addiction, attention deficit hyperactivity disorder (ADHD) and mood disorders.

Reducing the incidence of coronary heart disease

The incidence of coronary heart disease (CHD) has been significantly reduced by the introduction of the National Service Framework in 2000 but has not yet reached set targets. This article analyses the adverse effects of specific CHD risk factors to the cardiovascular system and proposes local and national strategies for further reduction in the incidence, morbidity and mortality of CHD. It provides an example of how nurses can use a health promotion programme to support patients in giving up smoking, a major contributing factor in CHD. The programme uses cognitive behaviour therapy to improve patients' uptake and adherence.

Habit reversal training as a treatment for refractory OCD - A case study

Nearly 4 million American men and women from all geographic, ethnic, or economic backgrounds are diagnosed with obsessive-compulsive disorder (OCD). While a combination of cognitive behaviour therapy (CBT) and psycho-pharmaca seems successful for 50% to 60% of patients, for intractable cases the typical recommendation is more medication or more CBT, however there is little evidence that the intensified treatment regimen is successful. In this paper, habit reversal training, including awareness training, competing/other response training, self-monitoring, social support, and generalisation, was implemented with a long-term treatment-refractory OCD patient. Treatment gains and long-term maintenance indicate the potential of habit reversal procedures with these patients.

Dipeptidyl peptidase IV (DPP IV) and related molecules in type 2 diabetes

Dipeptidyl peptidase IV (DPP IV) is a widely distributed physiological enzyme that can be found solubilized in blood, or membrane-anchored in tissues. DPP IV and related dipeptidase enzymes cleave a wide range of physiological peptides and have been associated with several disease processes including Crohn's disease, chronic liver disease, osteoporosis, multiple sclerosis, eating disorders, rheumatoid arthritis, cancer, and of direct relevance to this review, type 2 diabetes. Here, we place particular emphasis on two peptide substrates of DPP IV with insulin-releasing and antidiabetic actions namely, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). The rationale for inhibiting DPP IV activity in type 2 diabetes is that it decreases peptide cleavage and thereby enhances endogenous incretin hormone activity. A multitude of novel DPP IV inhibitor compounds have now been developed and tested. Here we examine the information available on DPP IV and related enzymes, review recent preclinical and clinical data for DPP IV inhibitors, and assess their clinical significance.

Psychological management of intractable seizures in an adolescent with a learning disability

Psychological interventions aimed at seizure management are described with a 14-year-old buy with a learning disability and intractable epilepsy. Baseline records suggested that a majority of tonic seizures and 'drop attacks' were associated with going off to sleep and by environmental 'startles'. Psychological formulation implicated sudden changes in arousal levels as an underlying mechanism of action. Cognitive-behavioural countermeasures were employed to alter arousal levels and processes in different ways in different 'at-risk' situations. A multiple baseline design was used to control for non-specific effects of interventions on non-targeted seizures. Results suggested significant declines in the number of sleep onset and startle-response seizures were attained by these methods. Gains were maintained at 2-month follow-up.

The Elasticity of Rehabilitation

This paper contributes to a debate on what constitutes rehabilitation. Current criminal justice practice tends to focus on lowering recidivism by utilising strategies geared towards cognitive behavioural modification and educational/vocational skill development. The paper focuses on the perspectives of custodial educators in a Juvenile Justice Centre in Northern Ireland. Their definition of rehabilitation is less concerned about lowering recidivism and instead focuses more on meeting the needs of the young people entering custody, more so than preparing them for their return to the community. Education staff present a model of rehabilitation that is fundamentally about improving the lives of young people. Despite expecting young people to return to custody Education staff contend that young people’s lives improved because they were exposed to a welcoming, caring and pro‐social environment which has helped the young people transform inttody.

Systematic review of interventions to improve the psychological well-being of general practitioners

BACKGROUND: The health of doctors who work in primary care is threatened by workforce and workload issues. There is a need to find and appraise ways in which to protect their mental health, including how to achieve the broader, positive outcome of well-being. Our primary outcome was to evaluate systematically the research evidence regarding the effectiveness of interventions designed to improve General Practitioner (GP) well-being across two continua; psychopathology (mental ill-health focus) and 'languishing to flourishing' (positive mental health focus). In addition we explored the extent to which developments in well-being research may be integrated within existing approaches to design an intervention that will promote mental health and prevent mental illness among these doctors.

METHODS: Medline, Embase, Cinahl, PsychINFO, Cochrane Register of Trials and Web of Science were searched from inception to January 2015 for studies where General Practitioners and synonyms were the primary participants. Eligible interventions included mental ill-health prevention strategies (e.g. promotion of early help-seeking) and mental health promotion programmes (e.g. targeting the development of protective factors at individual and organizational levels). A control group was the minimum design requirement for study inclusion and primary outcomes had to be assessed by validated measures of well-being or mental ill-health. Titles and abstracts were assessed independently by two reviewers with 99 % agreement and full papers were appraised critically using validated tools.

RESULTS: Only four studies (with a total of 997 GPs) from 5392 titles met inclusion criteria. The studies reported statistically significant improvement in self-reported mental ill-health. Two interventions used cognitive-behavioural techniques, one was mindfulness-based and one fed-back GHQ scores and self-help information.

CONCLUSION: There is an urgent need for high quality, controlled studies in GP well-being. Research on improving GP well-being is limited by focusing mainly on stressors and not giving systematic attention to the development of positive mental health.

Men’s strategies for preserving emotional well-being in advanced prostate cancer: an interpretative phenomenological analysis

Objective This study explores men with advanced prostate cancers’ own practices for promoting and maintaining emotional well-being using Interpretative Phenomenological Analysis. Design Five men with advanced prostate cancer participated in face-to-face, semi-structured, in-depth interviews. Results Within rich narratives of lost and regained well-being, two super-ordinate themes emerged – ‘living with an imminent and uncertain death’ and ‘holding on to life.’ Well-being was threatened by reduced sense of the future, isolation and uncertainty. Yet, the men pursued well-being by managing their emotions, striving for the future whilst enjoying life in the present, taking care of their families and renegotiating purpose. Running through participant’s accounts was a preference for taking action and problem-solving. Sense of purpose, social connectedness and life-engagement were revealed as concepts central to improving well-being, indicating areas which practitioners could explore with men to help them re-establish personal goals and life-purpose. Conclusions The findings also add weight to the evidence base for the potential value of psychological interventions such as cognitive behaviour therapy and mindfulness in men with prostate cancer.

The role of self-presentation in adolescent health risk behaviours

Self-presentation has been identified as playing a key role in the perfonnance of various potentially hazardous health behaviours such as substance abuse, eating disorders and reckless behaviours (Leary, Tchividjian, & Kraxberger, 1994; Martin & Leary, 2001; Martin, Leary, & O'Brien, 2001). The present study investigated the role of selfpresentation on adolescent health-risk behaviours. Specifically, this study examined the prevalence of adolescent identified health-risk behaviours rooted in self-presentational motives in youths aged 13-18 years. The current study also identified the specific images associated with these behaviours desired by youth, and the targets of these behaviours. Also, the relationship between these behaviours, and several trait measures (social physique anxiety, public-self consciousness, fear of negative evaluations, selfpresentational efficacy) of self-presentation were examined. Finally, the gender differences in health risk behaviours and self-presentational concerns were examined. Participants in the present study were 96 adolescent students, 34 male and 62 female, recruited from various private schools across Southern Ontario. Students ranged in age from 13 to 18 years for both males (M age = 15.81 years, SD = 1.49) and females (M age = 14.89 years, SD = 1.17) and ranged from grades 8 through 13. Results of the current study suggested that Canadian adolescents between the ages of 13 and 18 years participated in health risk behaviours for self-presentational purposes. Drinking alcohol, skipping school, and performing stunts and dares were identified as the most common health risk behaviours performed for self-presentational purposes by both males and females. Appearing fun and cool were the most commonly reported desired images while appearing brave and mature were the least reported. The most desired target group cited was same sex friends, followed by other sex friends. Trait measures of self-presentational concerns identified females as being higher in public self-consciousness, and social physique anxiety than males. Males were found to be higher in self-presentational efficacy than females. The total number of health risk behaviours was predicted by selfpresentational efficacy and social physique anxiety for males, and social physique anxiety for females. Findings of the current study suggest that Canadian adolescents' health risk behaviours are rooted, in part, in self-presentational motives. Thus far, an educational approach to health interventions has been favoured and/or adopted by teachers, health promoters, and educators (Jessor, 1992). Implications of the current study suggest that although educational interventions are beneficial in presenting the associated risks with certain activities and/or behaviours, one reason this type of approach may be ineffective in changing adolescent behaviour over the long run is that it does not address the strong and prominent influences of interpersonal motives on health damaging behaviour. It is evident that social acceptance and public image are of importance to adolescents, and the desire to make the "right" impression and to achieve peer approval and acceptance often override health and safety concerns (Jessor, 1992). Thus, a self-presentational approach focusing on changing the images associated with the behaviours may be more successful at deterring adolescent health risk behaviours.

"Weathering a hidden storm" : an application of Andersen's behavioral model of health, and health services use for those with diagnosable anxiety disorder

"Weathering a Hidden Storm": An App~ication of Andersen's Behaviora~ Mode~ of Hea~th, and Hea~th Services Use for Those With Diagnosab~e Anxiety Disorder Research has primarily focused on depression and mood disorders, but little research has been devoted to an examination of mental health services use amongst those with diagnosable anxiety disorder (Wittchen et al., 2002; Bergeron et al., 2005). This study examined the possible predicting factors for mental health services utilization amongst those with identifiable anxiety disorder in the Canadian population. The methods used for this study was the application of Andersen's Behavioral Model of Health Services Use, where predisposing, need and enabling 111 characteristics were regressed on the dependent variable of mental health services use. This study used the Canadian Community Health Survey (cycle 1.2: Mental Health and Well- Being) in a secondary data analysis. Several multiple logistics models predicted the likelihood to seek and use mental health services. Predisposing characteristics of gender and age, Enabling characteristics of education and geographical location, and those with co-occurring mood disorders were at the greatest increased likelihood to seek and use mental health services.

Associations between Exposure to Socio-Cultural Influences in Proximal Environments and Weight Concerns among Urban-Dwelling Women

Résumé Les préoccupations et comportements alimentaires entourant le poids sont omniprésentes chez les jeunes adolescentes et femmes qui habitent dans les cultures occidentales où les formes corporelles sont orientées vers un idéal ultra-mince. L’objectif de cette étude est d’examiner si une plus grande exposition aux endroits faisant la promotion de la minceur est associée à des préoccupations pour le poids plus élevées chez les femmes. Cette étude fait partie d’un projet intitulé ¨Social, cultural, and economic disparities and disordered eating: Understanding the contribution of neighbourhood and individual level factors¨ (Gauvin, Steiger, & Brodeur, 2009). Un échantillon de 1288 femmes âgées entre 20 et 40 ans et résidant à Montréal depuis au moins 12 mois ont répondu à un sondage téléphonique. Des régressions logistiques ont comparé les femmes se situant dans le quintile le plus élevé des préoccupations de poids avec les femmes dans les autres quintiles en fonction de leur exposition 15 jours ou plus dans des endroits faisant la promotion de la minceur. De plus, une analyse de sensibilité a vérifié si l’association demeurait significative à d’autres niveaux d’exposition. Les facteurs confondants ont été contrôlés statistiquement. Les résultats démontrent qu’une fréquentation d’au moins 15 jours par mois d’endroits faisant la promotion de la minceur est associée à des préoccupations plus élevées pour le poids. Aussi, fréquenter ces lieux entre 15 et 20 jours/mois est aussi associé à des préoccupations de poids élevées. Des interventions de santé publique pourraient viser la diminution des pressions socioculturelles vers la minceur.

Le rôle du sentiment d’efficacité personnelle, de l’insatisfaction corporelle et de l’alexithymie dans l’étiologie et le maintien des troubles des conduites alimentaires

La forte prévalence des troubles des conduites alimentaires (TCA) chez les jeunes femmes et les faibles taux de rémission suite à un traitement ont encouragé les chercheurs à mieux comprendre les facteurs impliqués dans ce trouble mental. L’un des premiers modèles à mettre l’emphase sur des traits de personnalité associés au développement d’un TCA a été proposé par Hilde Bruch (1962, 1973, 1978) et a toujours une grande influence dans la recherche actuelle. Le modèle de Bruch inclue trois facteurs, soit l’insatisfaction corporelle, l’inefficacité et la conscience intéroceptive. Le but de cette thèse est d’apporter un support empirique au modèle de Bruch. En se basant sur une revue extensive des écrits scientifiques, cette thèse vise aussi à déterminer si deux facteurs reliés, soit l’alexithymie et le sentiment d’efficacité personnelle face à l’adoption de conduites alimentaires saines, améliorent la précision du modèle dans la prédiction de symptômes de TCA. Pour répondre empiriquement à cette question, il était d’abord nécessaire de disposer d’un questionnaire évaluant le sentiment d’efficacité personnelle en lien avec les conduites alimentaires qui peut être utilisé dans tout le spectre de présentation des TCA. Ainsi, le Eating Disorder Self-Efficacy Questionnaire (EDRSQ) a été adapté en français et ses propriétés psychométriques ont été évaluées. Une analyse factorielle confirmatoire a révélé une structure bi-factorielle, soit le sentiment d’efficacité personnelle en lien avec l’insatisfaction corporelle et avec l’adoption d’une alimentation normative. Chaque échelle a démontré une bonne fiabilité ainsi qu’une validité de construit cohérente avec la théorie. Par la suite, la capacité des facteurs proposés par Bruch à prédire les symptômes de TCA a été évaluée et comparée à des adaptations du modèle découlant des écrits. Au total, 203 étudiantes de premier cycle universitaire ont complété les versions validées en français du Eating Disorder Inventory 2, du Eating Attitudes Test, et du Toronto Alexithymia Scale en plus du EDRSQ. Les résultats montrent que le modèle de Bruch explique 46% de la variance des symptômes de TCA. Alors que l’insatisfaction corporelle et la conscience intéroceptive démontrent chacun une contribution importante dans la prédiction des symptômes de TCA, il a été démontré que l’inefficacité présente seulement une contribution spécifique négligeable. Le modèle de Bruch est amélioré par la substitution de l’inefficacité par le sentiment d’efficacité personnelle tel que mesuré par le EDRSQ; le modèle explique alors 64% de la variance des symptômes de TCA. Finalement, cette étude démontre que l’alexithymie n’a pas de contribution spécifique dans la prédiction des symptômes de TCA. Ainsi, la combinaison d’une faible conscience intéroceptive, de l’insatisfaction corporelle et d’un faible sentiment d’efficacité personnelle en lien avec les conduites alimentaires est fortement associée aux symptômes de TCA dans un échantillon non-clinique de jeunes femmes. Finalement, les implications conceptuelles et cliniques de ces résultats sont discutées.
