Measuring Self-Control Beliefs: A Multidimensional and Domain-Specific Perspective.

We tested unique contribution of trait self-control, implicit self-control, and lay beliefs in self-control beliefs to the prediction of health-related behaviours. We also tested whether relations between trait self-control and health-related behaviour, and between implicit self-control and health-related behaviours, were moderated by self-control beliefs. Cross-sectional, correlational. Students (N=176) completed self-report measures of trait self-control, lay beliefs that self-control is limited or non-limited, non-planning, participation in health-related behaviours (impulsive eating, impulsive drinking, exercise avoidance, watching diet, alcohol consumption, physical activity participation), and demographic variables. Participants also completed a measure of implicit self-control using an implicit association test. Analyses indicated significant negative relations between implicit self-control and impulsive drinking and alcohol consumption. We also found a positive relationship between implicit self-control and exercise behaviour, and a negative relationship between implicit self-control and impulsive eating, both of which fell marginally short of statistical significance. Trait self-control significantly predicted all behavioural measures and attenuated relations between implicit self-control and health-related behaviour. We found no relations between lay beliefs in self-control and health-related behaviour. Moderated path analyses revealed that lay beliefs in self-control moderated relations between trait self-control and impulsive drinking, implicit self-control and exercise avoidance, and implicit self-control and physical activity participation. Findings suggest that trait self-control was a consistent correlate of health-related behaviour, while the effect sizes of relationships between implicit self-control and health-related behaviours were small. Strength of relations between trait self-control and health-related behaviours may depend on whether or not individuals believe self-control is limited. Statement of contribution What is already known on this subject? Self-control represents individuals capacity to override impulses, break habits, and avoid temptations. Trait self-control is consistently and positively related to uptake of health-promoting behaviours (e.g., physical activity, healthy eating). Trait self-control is consistently and negatively related to health-compromising behaviours (e.g., alcohol consumption, unhealthy snacking). What does this study add? Proposes that self-control can also be measured implicitly, beyond individuals' awareness. Examined effects of implicit measures of self-control and self-reported trait self-control on multiple health behaviours. Effects of implicit self-control on health behaviours were small and subsumed by trait self-control. Effects of lay beliefs in self-control moderated effects of implicit and trait self-control on some health behaviours.

Three studies (N = 555) examined whether emotion regulation and emotions help people higher in trait self-control (TSC) to achieve their goals. Because emotion utility beliefs predict emotion regulation and performance, Study 1a examined whether TSC predicts emotion utility beliefs in two performance contexts, and Study 1b examined whether these beliefs predict preferences to regulate emotions. Study 2 examined whether TSC predicts choice to regulate emotions, and how choice and emotions influence self-control performance. While TSC did not predict emotion regulation, people higher in TSC considered positive (negative) emotions more (less) useful and experienced more (less) positive (negative) emotion after an emotion regulation task, which enhanced their self-control performance. This research underscores the role of emotion regulation and emotions in self-control.

This study aimed to assess the plausibility of self-control depletion, or ego-depletion, as the underlying cognitive resource responsible for performance decrements on the sustained attention to response task. Researchers suggested that self-control is a limited cognitive resource used to complete a myriad of processes, including sustained attention. Past research showed that trait self-control affects some sustained attention tasks. However, little research has investigated the effect of self-control as a limited cognitive resource that varies over time (i.e., as a state-dependent variable). This experiment investigated the effect of self-control (trait and state) on a sustained motor-inhibition task (e.g., sustained attention to response task; SART). State self-control was manipulated using a between-subjects design-participants in the experimental condition completed a task designed to deplete state self-control prior to performing the SART while the control condition completed a modified version that did not deplete self-control. Trait self-control predicted performance on the SART, but the depletion task (state self-control) had no detectable effect. Given the evidence, it is unlikely that state self-control plays a causal role in performance decrements in the SART, but there appears to be some association between performance on the SART and trait self-control. Trait self-control ought to be considered in future work for personnel selection in real-world tasks that the SART models such as long-distance driving, air traffic control, and TSA operations.

Does trait self-control (TSC) predict affective well-being and life satisfaction--positively, negatively, or not? We conducted three studies (Study 1: N = 414, 64% female, Mage = 35.0 years; Study 2: N = 208, 66% female, Mage = 25.24 years; Study 3: N = 234, 61% female, Mage = 34.53 years). The key predictor was TSC, with affective well-being and life satisfaction ratings as key outcomes. Potential explanatory constructs including goal conflict, goal balancing, and emotional distress also were investigated. TSC is positively related to affective well-being and life satisfaction, and managing goal conflict is a key as to why. All studies, moreover, showed that the effect of TSC on life satisfaction is at least partially mediated by affect. Study 1's correlational study established the effect. Study 2's experience sampling approach demonstrated that compared to those low in TSC, those high in TSC experience higher levels of momentary affect even as they experience desire, an effect partially mediated through experiencing lower conflict and emotional distress. Study 3 found evidence for the proposed mechanism--that TSC may boost well-being by helping people avoid frequent conflict and balance vice-virtue conflicts by favoring virtues. Self-control positively contributes to happiness through avoiding and dealing with motivational conflict.

Previous research found that performing an initial self-control task impairs subsequent self-control performance, which is referred to as ego depletion. However, recent meta-analyses and replication studies have led to controversies over whether the ego depletion effect is as reliable as previously assumed. The present study aimed to shed more light on these controversies by combining depletion measurement task type and personality as moderators. Study 1 investigated trait self-control and action orientation's moderation role for depletion effects on stop-signal task (inhibitory control). Study 2 examined the trait self-control and action orientation's moderation role for depletion effects on a majority congruent Stroop task (goal maintenance). Results showed that trait self-control moderated the ego depletion effect on stop-signal reaction time (SSRT). High trait self-control people were less vulnerable to the ego depletion effect on the reactive inhibitory control task, whereas the moderating role of trait self-control for ego depletion was not found in the goal maintenance task. More particularly, high action-oriented people were less susceptible to the ego depletion effect on the goal maintenance task, but there was no moderation effect of action orientation for ego depletion in the stop-signal task. We discuss types of task for depletion measurement and individual differences in ego depletion, and we suggest possible avenues for future research.

Exerting self-control in a first task weakens self-control performance in a subsequent unrelated task (ego depletion). In self-control research new strategies are required to investigate the ego-depletion effect, which has recently been shown to be more fragile than previously assumed. Moreover, the relation between ego depletion and trait self-control is still unclear, as various studies have reported heterogeneous findings concerning the interplay of both variables. We addressed these lacunas by drawing on a sample of N = 120 students, who participated in two test sessions. In the first test session, we assessed trait self-control and several control variables. The second test session followed an experimental design and tested the effects of ego depletion on invested effort and cognitive performance trajectories in an ecologically valid computer-based assessment setting (i.e., a 30-minute mathematical problem-solving and reasoning test). Trait self-control was then used as a moderator of the ego-depletion effect. Combining an established ego-depletion paradigm (i.e., the sequential-task paradigm) with multilevel modeling of time-on-task and performance changes, our results indicate (1) that trait self-control predicted the motivation to solve cognitive tasks, (2) that ego depletion led to a progressive performance decrease, and (3) that the negative effect of ego depletion on performance was stronger for students with high trait self-control. Additional analyses revealed that our results could not be alternatively explained by fatigue effects. All effects were robust even after controlling for the students’ cognitive abilities, which are known to be closely related to mathematical performance. Our results provide evidence that the self-control invested in order to keep performance at a consistently high level wanes over time. By modeling progressive ego-depletion effects while considering trait self-control, we provide an alternative approach that may help future researchers to investigate the underlying mechanisms of self-control.

Most discussions of self-control have focused on its benefits rather than its costs. The most important cost appears to be the depletion of limited self-control resources. Acts of self-control both consume and require self-control resources, and, until these resources can be replenished, people's ability to perform many adaptive behaviors is compromised. These impairments affect not only self-control but also intelligent thought, effective decision making, and initiative. The limited resource itself presents further potential costs, insofar as the person must manage the limited resource (e.g., conserving for future demands), and managing the resource itself is presumably another demand for self-regulation and hence a drain on the limited resource. Trait self-control, in contrast, appears to have few or no downsides.

The multiple pathways by which self-control predicts behavior

The research within this thesis focused on examining the concept of self-control; the ability of regulating and/or controlling responses, e.g. choosing a fruit salad rather than a more tempting chocolate cake. Self-control was of interest as evidence has repeatedly observed that the ability to apply self-control continually over time poses difficulty. Namely, when faced with completing two sequential tasks that both require self-control, typically prior research reported that the first task is completed successfully but there is a temporary impairment in self-control performance in the second. The work in this thesis attempted to address why a temporary deterioration in self-control performance occurs. Specifically, we drew on the strength model, which posits that self-control is directly fuelled by a limited resource that gets depleted when initially applied, leaving limited resources available for the second task. Glucose was proposed – though with recent debate - as the physiological resource and consequently we assessed the role of glucose in sequential self-control task performance. In addition evidence suggested that rather than self-control deterioration stemming from resource depletion, it is connected to a reluctance to allocate resources based on a lowering in intrinsic motivation. The seven studies that were conducted attempted to further examine and add to the debate about the factors that play a role in self-control depletion following prior exertion, with a specific focus on the effects of glucose and intrinsic motivation. Overall the findings from the studies somewhat challenge the direct role of glucose: no relationship between glucose and sequential self-control performance was observed. Intrinsic motivation was however predicted to be a stronger predictor of self-control ability over time, suggesting that perhaps the temporary deterioration in self-control performance is one of resource allocation rather than depletion. More research is needed to corroborate these findings but the accumulation of evidence within this thesis - added to the current research - supports more of the recent literature i.e. motivation plays an important role in successful self-control exertion.

Self-control is defined as the capacity to override natural and automatic tendencies; and to conscious control one’s behavior. The strength model of self-control suggests that the exertion of self-control depends on a limited resource. Research has supported the strength model in the domains of impulsive behaviors, interpersonal processes, decision making and judgments. Factors that appear to have impact on the self control strength include personality, emotion, motivation and self-control programs. It is necessary to identify the difference between fatigue and ego depletion and to access the contributions of motivation and beliefs in self control in the future research. Finding a reliable way to improve self-control in real world settings would be another helpful direction for further work.

Motivational foundations of self-control and mindfulness and their role in study–leisure conflicts

Chapter 11 - Implicit Theories About Willpower

This paper draws on work in the sciences of the mind to cast doubt on some assumptions that have often been made in the study of self-control. Contra a long, Aristotelian tradition, recent evidence suggests that highly self-controlled individuals do not have a trait very similar to continence: they experience relatively few desires that conflict with their evaluative judgments and are not especially good at directly and effortfully inhibiting such desires. Similarly, several recent studies have failed to support the view that self-control capacities are constituted, at least in part, by excellent inhibitory executive function ability. I propose an alternative “indirect harmony” hypothesis about trait self-control. According to this hypothesis, if there is a character trait of being highly self-controlled, it consists in motivational harmony within the mind that is brought about through the effective use of indirect resistance strategies that prevent occurrent motivational conflict from emerging in the first place. If this hypothesis is correct, high trait self-control in actual humans does not fit neatly into the traditional categories of either continence or temperance. I conclude by drawing out several implications this hypothesis has for future research on trait self-control and its relation to executive functions.

Gaming disorder and depression of Chinese adolescents have aroused widespread concern. Although there is a close relationship between gaming disorder and depression among ordinary adolescents, few studies have examined this relationship among Chinese left-behind adolescents (adolescents left in rural areas while parents work in urban areas for at least six months annually) from the perspective of environment-individual interactions. This study aimed to analyze whether family, school, and personality factors could interact in predicting left-behind adolescents’ gaming disorder and depression. A cross-sectional questionnaire study was conducted between June and December 2020 in four high schools in Central China. A total of 618 left-behind adolescents between 11 and 15 years of age completed the anonymous survey. The results found that gaming disorder acted as a mediator linking parental neglect to depression. Teacher-student relationships and trait self-control uniquely weakened the predictive effect of parental neglect on gaming disorder and the mediating effect of gaming disorder between parental neglect and depression. The three-way interaction of parental neglect, teacher-student relationships, and trait self-control also showed a significant effect on left-behind adolescents’ depression through gaming disorder. The protective role of teacher-student relationships on the mediation of gaming disorder was stronger for left-behind adolescents with lower trait self-control, and the protective role of trait self-control on the mediation of gaming disorder was stronger for left-behind adolescents with lower teacher-student relationships. The results promote a better understanding of how family, school, and personality interact to predict left-behind adolescents’ gaming disorder and depression. The findings can inform specific practical suggestions for preventing and intervening in gaming disorder and depression.
