“…Failing to establish group cohesion and a positive group atmosphere might decrease engagement with the programme, leading to lower attendance and retention. This is particularly important as negative group dynamics, such as group conflict, have been linked with lower weight loss, attendance, and adherence (Nackers et al, 2015).…”

What is already known on this subject?Many health interventions, including programmes to help prevent or manage diabetes and facilitate weight loss, are delivered in groups. Such group-based behaviour-change interventions are often effective in facilitating psychological and behaviour change. There is considerable research and theory on individual change processes and techniques, but less is known about which change processes and techniques facilitate behaviour change in group settings. What does this study add?This study contributes to our understanding of how participating in group-based health programmes may enhance or impede individual behaviour change. It identified individual (intrapersonal) and group (interpersonal, facilitated through group interaction) change processes that were valued by group participants. The findings also show how these change processes may be affected by the group context. A diagram summarizes the identified themes helping to understand interactions between these key processes occurring in groups.The study offers an insight into participants' views on, and experiences of, attending a group-based diabetes prevention and management programme. Thus, it helps better understand how the intervention might have helped them (or not) and what processes may have influenced intervention outcomes. Key practical recommendations for designing and delivering group-based behaviour-change interventions are presented, which may be used to improve future group-based health interventions.

“…Other factors may also influence intervention effectiveness. For example, conflict in the groups (Nackers et al, 2015), establishment of specific group norms (Cruwys, Haslam, Fox, & McMahon, 2015) or degree of identification with the group (Wakefield, Bickley, & Sani, 2013). However, poor reporting of group characteristics in primary studies, methodological limitations of those studies, and the heterogeneous nature of the groups categorised as either having, or not having, particular characteristics make it difficult for meta-analyses to identify mechanisms of change in GB-BCIs (see Borek, Abraham, Smith, Greaves, & Tarrant, 2015;Borek et al, 2018).…”

Background: Small groups are used to promote health, well-being, and personal change by altering members' perceptions, beliefs, expectations, and behaviour patterns. An extensive cross-disciplinary literature has articulated and tested theories explaining how such groups develop, function, and facilitate change. Yet these theoretical understandings are rarely applied in the development, description, and evaluation of health-promotion, group-based, behaviour-change interventions. Methods: Medline database, library catalogues, search engines, specific journals and reference lists were searched for relevant texts. Texts were reviewed for explanatory concepts or theories describing change processes in groups, which were integrated into the developing conceptual structure. This was designed to be a parsimonious conceptual framework that could be applied to design and delivery. Results: Five categories of interacting processes and concepts were identified and defined: (1) group development processes, (2) dynamic group processes, (3) social change processes, (4) personal change processes, and (5) group design and operating parameters. Each of these categories encompasses a variety of theorised mechanisms explaining individual change in small groups. Conclusion: The final conceptual model, together with the design issues and practical recommendations derived from it, provides a practical basis for linking research and theory explaining group functioning to optimal design of group-based, behaviour-change interventions.

“…En general, en els articles revisats, la durada és d'uns 6 mesos de tractament, però hi ha variabilitat amb tractaments de 10 setmanes, 3 mesos o 2 anys, amb seguiment d'un fins a 8, 5 anys. El format d'intervenció pot ser individual i/o grupal, tot i que sembla que les intervencions grupals són millors per a la pèrdua de pes, sempre que no hi haja conflictes d'interrelació entre els membres del grup, atès que el suport mutu i el sentiment de pertinença a un grup és un gran al·licient motivacional (Nackers i al., 2015).…”

ResumIntroducció: l'obesitat és una patologia en augment amb greus conseqüències per a la salut, per la qual cosa és necessari aprofundir en la seua comprensió i millorar els seus tractaments. Nombrosos autors proposen tractaments multidisciplinaris que incorporen en la intervenció les diferents varia bles que estan associades a l'obesitat.Mètode: revisió d'articles nacionals i internacionals que analitzen les característiques i eficàcia de diversos tractaments multidisciplinaris de l'obesitat, usant les bases de dades de PsycINFO i ScienceDirect. La recerca s'ha centrat en les publicacions dels últims 10 anys relacionades amb l'obesitat i el seu tractament. Dels 21.012 articles trobats en un primer filtre, es va establir pp. 123-142 Resultats: els tractaments multidisciplinaris -psicologia, nutrició, exercici i supervisió mèdica-són eficaços, i més que els que apliquen disciplines aïllades. Mantenen una bona adherència del pacient, amb pèrdues de pes adequades, reducció de les complicacions físiques, i manteniment a llarg termini dels resultats aconseguits, a més que la pèrdua de pes condueix a millores en l'estat mental i viceversa. S'analitzen les característiques d'aquests tractaments, localitzant les estratègies més adequades i les àrees d'intervenció treballades i, amb açò, es planteja una proposta d'intervenció multidisciplinària -psiconutricional-per a l'obesitat.Conclusions: l'obesitat no és aliena als factors psicològics. Es essen cial promoure intervencions multidisciplinàries per augmentar l'eficàcia dels tractaments i el manteniment dels èxits.
