Group-size-dependent punishment of idle subordinates in a cooperative breeder where helpers pay to stay.

ABSTRACT: In cooperative breeding systems, dominant breeders sometimes tolerate unrelated individuals even if they inflict costs on the dominants. According to the 'pay-to-stay' hypothesis, (i) subordinates can outweigh these costs by providing help and (ii) dominants should be able to enforce help by punishing subordinates that provide insufficient help. This requires that dominants can monitor helping and can recognize group members individually. In a field experiment, we tested whether cooperatively breeding cichlid Neolamprologus pulcher subordinates increase their help after a forced 'idle' period, how other group members respond to a previously idle helper, and how helper behaviour and group responses depend on group size. Previously, idle helpers increased their submissiveness and received more aggression than control helpers, suggesting that punishment occurred to enforce help. Subordinates in small groups increased their help more than those in large groups, despite receiving less aggression. When subordinates were temporarily removed, dominants in small groups were more likely to evict returning subordinates. Our results suggest that only in small groups do helpers face a latent threat of punishment by breeders as predicted by the pay-to-stay hypothesis. In large groups, cognitive constraints may prevent breeders from tracking the behaviour of a large number of helpers.

Project description:IntroductionMost smoking quit attempts end in relapse, and interventions focused on relapse prevention are lacking. Helpers Stay Quit (HSQ) is a novel behavioral relapse prevention intervention that teaches newly abstinent smokers to offer a "helping conversation" (HC) to help others quit tobacco.MethodsPre-post intervention feasibility study with state quitline participants ≥14 days abstinent. Measures at baseline, 3 months, and 6 months included smoking status, offering HCs, and cessation self-efficacy. Primary outcomes: self-reported 7-day point prevalence abstinence; offering HCs. Cox models explored association of HCs with relapse. Preliminary effects analysis using propensity score matching compared 30-day abstinence of quitline clients with study sample at 7 months.ResultsParticipants (N = 104) were as follows: mean age of 53 years (SD 13.9 years), 48.1% male, mean of cigarettes smoked/day of 16.2 (SD 9.7). Compared with participants who remained abstinent (n = 82), relapsers (n = 22) had fewer HCs over 6 months (2.6 vs 7.2; 95% confidence interval [CI]: 1.4, 7.8, p = .006). Using adjusted Cox regression, the hazard ratio of relapse for each HC was 0.85 (95% CI: 0.74, 0.99, p = .03). Compared with a matched sample of quitline clients not exposed to HSQ, study participants were 49% more likely to report 30-day abstinence at 7-month quitline follow-up (95% CI: 40%, 59%, p < .0001).ConclusionsHSQ, delivered to newly abstinent smokers who received standard quitline treatment, was associated with less self-reported relapse. These promising preliminary study results warrant further research to evaluate HSQ as a novel behavioral intervention to prevent smoking relapse.ImplicationsTo date, behavioral interventions for smoking relapse prevention that teach abstainers cessation skills to apply to themselves have not shown effectiveness. This feasibility study examines the preliminary efficacy of a conceptually novel, "help others" behavioral intervention approach for relapse prevention in newly abstinent smokers recruited from a state quitline. HSQ teaches the newly abstinent smoker communication and listening skills to encourage other smokers in their personal social network to quit. Exploratory analysis using propensity score matching suggests that participants exposed to HSQ were significantly more likely to self-report 30-day abstinence at quitline 7-month follow-up than other quitline clients.
