A comprehensive model of the telecommuting adoption process, incorporating employer and employee perspectives, is developed. A probabilistic modeling approach is taken. The employer decision to offer a telecommuting program is modeled as a function of motivations and constraints and of the perceived impacts of telecommuting on the organization's productivity and costs. The employee decision to adopt telecommuting is modeled as a function of motivations and constraints as well as of the impact of the program on lifestyle quality, work-related costs, and income. The results indicate that telecommuting has a significant potential to increase productivity and improve lifestyle quality, if the right program is designed for the right employee. The potential of telecommuting to reduce organization and employee work-related costs is perceived to be limited. An overall negative perception about the potential impact on productivity and lifestyle quality of telework center–based telecommuting programs is identified, pointing to a need for further research to assess the market for telework centers.

ResumoObjetivo: Potencial moderador e mediador da eficácia nas intervenções para perda de peso bem-sucedida (PPBS), o suporte social é poucas vezes avaliado neste contexto. Pretende-se averiguar a relação entre a percentagem de peso perdido e variáveis sociodemográficas e psicológicas, incluindo satisfação com o suporte social, em pessoas que realizaram uma PPBS. Método: No total, 105 adultos com PPBS (ou seja, perda igual ou superior a 7% do peso inicial, com manutenção mínima de 12 meses) preencheram a Escala de Satisfação com o Suporte Social e um questionário para recolha de informação sociodemográfica, estado de saúde psicológica e estilos de vida. Resultados: O modelo estrutural com as dimensões de satisfação com a família e intimidade apresentou um bom ajustamento (χ 2 /gl = 1,343; CFI = 0,943; GFI = 0,924; RMSEA = 0,057, p < 0,001; C.I. 90% = ]0,000; 0,093[); a satisfação com o suporte familiar (β = 0,193; p = 0,081) e a existência de uma relação afetivo-sexual (β = -0,184; p = 0,082) foram as únicas variáveis a predizer marginalmente a percentagem de peso perdido. Conclusão: Participantes mais satisfeitos com o suporte familiar (no mínimo, um ano após a PPBS) perderam uma maior percentagem de peso; assim, a satisfação com suporte social da família poderá ser uma variável relevante no processo de perda de peso. Todavia, a natureza do estudo (tipo de estudo e de amostra) torna necessária mais investigação na área para confirmar este resultado.Palavras-Chave: perda de peso bem-sucedida, satisfação com o suporte social, satisfação com o suporte familiar Abstract Aim: As a potential moderator and mediator of the effectiveness of interventions for successful weight losses (SWL), which is rarely assessed in this context, we aimed to examine the relation between the percentage of weight loss and psychological and socio-demographic variables, including satisfaction with social support, in people who accomplished a SWL. Method: A total of 105 adults with a SWL (that is, a loss equal or superior to 7% of the initial weight, sustained for at least 12 months) filled the Satisfaction with Social Support Scale and a questionnaire, in order to collect socio-demographic, psychological health status and life style information. Results: The structural model with the dimensions of satisfaction with family support and intimacy present a good adjustment (χ 2 /gl = 1,343; CFI = 0,943; GFI = 0,924; RMSEA = 0,057, p < 0,001; C.I. 90% = ]0,000; 0,093[); satisfaction with family support (β = 0,193; p = 0,081) and the presence of a sexual-affective relationship (β = -0,184; p = 0,082) were the only variables to marginally predict the percentage of lost weight. Conclusion:The participants who were more satisfied with family support (at least one year after the SWL) lost a greater percentage of weight; therefore, satisfaction with family social support might be a relevant variable in the weight loss process. However, the nature of the study (type of study and sample) demands further research to corroborate this results.
