My future-self has (not) quit smoking: An experimental study into the effect of a future-self intervention on smoking-related self-identity constructs.

OBJECTIVES: Envisioning one's (non)smoking future may make (un)desired future identities more accessible, salient, and personally relevant and facilitate smoking cessation. The current study assessed whether a future-self intervention can weaken smoker self-identity and expected identity loss when quitting smoking, and strengthen quitter- and nonsmoker self-identity, while accounting for personal factors-socioeconomic position, nicotine dependence, consideration of future consequences, and clarity of the envisioned future-self. Additionally, it examined the association between smoking-related identity and quitting intention and behavior. METHODS: This longitudinal online experimental study randomized 233 adult smokers to an intervention condition (where they completed mental imagery, visual, and verbal tasks about a future (non)smoking self), or to a passive control condition. Smoker-, quitter-, nonsmoker self-identity and identity loss were measured post-intervention and after one- and three-months. Quit intention and attempts were measured at baseline and after one month. RESULTS: There was a consistent increase in non-smoker self-identity, and decrease in smoker self-identity and identity loss over a period of six months for all participants, but no significant difference in smoking-related identity between the intervention and control group. While personal factors did not moderate the effect of the intervention, we found that smoking-related identity constructs do vary with nicotine dependence, consideration of future consequences, and clarity of the envisioned future-self. Quitting behavior is primarily associated with non-smoker self-identity. CONCLUSIONS: Although the future-self intervention did not significantly influence smoking-related identity or behavior, identity-in particular, non-smoker self-identity-is important to consider in smoking cessation interventions. More research is needed to find effective operationalizations for identity-based interventions in the context of smoking.

Testing an attachment- and trauma-informed intervention approach for parents and young children after interparental violence: protocol for a randomized controlled trial.

BACKGROUND: Interparental violence has persistent adverse effects on victimized parents and children. Young children, including infants and toddlers, are at particular risk to develop long-lasting negative outcomes, and yet specific evidence on effective intervention approaches for this vulnerable group is still lacking. This study will test the effectiveness of an attachment- and trauma-informed intervention approach in a sample of parent-child dyads who have experienced severe interparental violence. We test the individual and combined effects of two interventions: (1) "Nederlandse Interventie Kortdurend op Atypisch oudergedrag" (NIKA; Dutch, short-term intervention focused on atypical parenting behavior) aimed at improving the attachment relationship and (2) eye movement desensitization and reprocessing (EMDR) therapy aimed at reducing parental post-traumatic stress disorder (PTSD) symptoms. METHODS: This study uses a multicenter randomized controlled design across multiple domestic violence shelters in the Netherlands. We aim to recruit 150 parent-child dyads with children aged between 0.5 and 6 years old. The study design consists of two phases. During the first phase for testing the effect of NIKA only, eligible dyads are randomly allocated to either NIKA or a waitlist usual care group. A pre-test is conducted prior to the treatment period and a post-test takes place directly afterwards (6 weeks after the pre-test). Phase 2 follows directly for testing the effects of EMDR and the combination of NIKA and EMDR. Parents who report clinical PTSD symptoms are randomly allocated to either EMDR therapy or a waitlist usual care group. Parents who do not report clinical PTSD symptoms only receive care as usual. Six weeks later, a post-test of phase 2 is conducted for all participating dyads. Primary study outcomes are disrupted parenting behavior, sensitive parenting behavior, and parental PTSD symptoms. Secondary study outcomes include PTSD symptoms and behavioral and emotional problems of the child. DISCUSSION: This study will inform and enhance the clinical field by providing new insights regarding effective treatment combinations for traumatized parents and their young children after interparental violence.
