Correlation of exercise participation, behavioral inhibition and activation systems, and depressive symptoms in college students

To clarify the pathways and effects of the behavioral inhibition and activation systems in the relationship between exercise participation and depressive symptoms among college students. A cross-sectional research design was employed to survey 2606 college students using physical activity questionnaires, the Behavioral Inhibition/Activation Systems Scale, and the Beck Depression Inventory. Data were analyzed using methods including one-way ANOVA, independent sample t-tests, non-parametric tests, chi-square tests, correlation analysis, and structural equation modeling. Depressive symptoms were significantly negatively correlated with exercise participation (r = − 0.107, P < 0.001), reward responsiveness (r = − 0.201, P < 0.001), drive (r = − 0.289, P < 0.001), and fun seeking (r = − 0.102, P < 0.001), and positively correlated with behavioral inhibition (r = 0.084, P < 0.001). Exercise participation was positively correlated with reward responsiveness (r = 0.067, P = 0.001), drive (r = 0.085, P < 0.001), and fun seeking (r = 0.063, P = 0.001). Exercise participation had a significant direct effect (B = − 0.079, 95% CI − 0.116 to − 0.043) and total effect (B = − 0.107, 95% CI − 0.148 to − 0.069) on depressive symptoms. The mediating effects of drive (B = − 0.028, 95% CI − 0.043 to − 0.016) and fun seeking (B = 0.005, 95% CI − 0.001 to 0.011) were significant. The more college students engage in exercise, the lower their depressive symptom scores. Drive and fun seeking mediate the relationship between college students' exercise participation and depressive symptoms. Encouraging exercise participation among college students and enhancing their sensitivity to behavioral activation strategies and reward information may have a significant role in preventing and alleviating depressive symptoms.

Psychological distress in a sample of predominately white female college students: the role of mindfulness and physical activity

Objective: Framed in Reinforcement Sensitivity Theory, this study examined the moderating effects of mindfulness and moderate-to-vigorous physical activity (MVPA) on the relationship between behavioral inhibition system (BIS) sensitivity and psychological distress in college students. Participants: Undergraduate students (n = 183) at a large public university in the United States were included in the study. Methods: Self-reported BIS sensitivity, mindfulness, MVPA, and psychological distress were examined in November 2021. Results: Findings revealed a positive relationship between BIS sensitivity and psychological distress, however, this relationship was conditional on levels of mindfulness and MVPA. Specifically, increased reports of mindfulness and MVPA related to lower psychological distress for participants with higher than average BIS sensitivity. Conclusions: Mindfulness and MVPA are buffers for university students prone to psychological distress. Identifying diverse strategies that effectively lower psychological vulnerabilities in college students can be used to develop targeted interventions that reduce psychopathology and promote mental health.

Relations of behavioral inhibition and activation system sensitivities with vaccination outcomes: Investigating the mediating role of vaccine hesitancy in older adults.

The study of behavioral inhibition system (BIS) and behavioral activation system (BAS) sensitivities has produced a multitude of models and frameworks to better understand decision-making and behavior. We extend this research to the study of a vaccination by exploring the relation of BIS and BAS sensitivities with vaccination willingness, receipt, and word-of-mouth. We also assess whether dimensions of vaccine hesitancy mediate these relations, testing whether they are viable explanatory mechanisms. By conducting a multi-wave survey study, our results support that BIS sensitivity does not meaningfully relate to vaccine hesitancy or vaccination outcomes. On the other hand, BAS sensitivity related to detrimental vaccination outcomes, and these effects were mediated by vaccine hesitancy dimensions associated with perceptions that vaccines cause health risks and are not needed for healthy individuals. Based on extant BIS and BAS theory, these results suggest that certain people may see refraining from vaccination as a nonpunishment.

Network Analysis of Behavioral Activation/Inhibition Systems and Brain Volume in Individuals With and Without Major Depressive Disorder or Social Anxiety Disorder

BackgroundSocial anxiety disorder (SAD) and major depressive disorder (MDD) are characterized by behavioral abnormalities in motivational systems, namely the behavioral inhibition system (BIS) and behavioral activation system (BAS). Limited studies indicate brain volume in regions that support emotion, learning/memory, reward, and cognitive functions relate to BIS/BAS. To increase understanding of BIS/BAS, the current study used a network approach. MethodsPatients with SAD (n = 59), patients with MDD (n = 64), and healthy control participants (n = 36) completed a BIS/BAS questionnaire and structural magnetic resonance imaging scans; volumetric regions of interest comprised cortical and limbic structures based on previous BIS/BAS studies. A Bayesian Gaussian graphical model was used for each diagnostic group, and groups were compared. Among network metrics, bridge centrality was of primary interest. Analysis of variance evaluated BIS/BAS behaviors between groups. ResultsBridge centrality showed hippocampus positively related to BAS, but not to BIS, in the MDD group; no findings were observed in the SAD or control groups. Yet, network density (i.e., overall strength of relationships between variables) and degree centrality (i.e., overall relationship between one variable to all other variables) showed that cortical (e.g., precuneus, medial orbitofrontal) and subcortical (e.g., amygdala, hippocampus) regions differed between diagnostic groups. Analysis of variance results showed BAS was lower in the MDD/SAD groups compared with the control group, while BIS was higher in the SAD group relative to the MDD group, which in turn was higher than the control group. ConclusionsPreliminary findings indicate that network-level aberrations may underlie motivational abnormalities in MDD and SAD. Evidence of BIS/BAS differences builds on previous work that points to shared and distinct motivational differences in internalizing psychopathologies.

Comparison of behavioral activation/inhibition systems, emotional regulation difficulties, and selective attention in adolescents with and without parents.

Existing literature has established a relationship between adverse childhood experiences and negative outcomes in cognitive and affective functioning. However, further research is needed to thoroughly understand and validate these findings. In this regard, the current study aimed to compare behavioral activation/inhibition systems, emotional regulation difficulties, and selective attention in adolescents with and without parents. A sample of 70 adolescents (M age = 16.36, SD = 1.09, 48.57% female) with caretakers from schools and 55 parentless adolescents (M age = 16.58, SD = 1.28, 52.00% female) from orphanage centers in Tehran were recruited and completed the measures tapping behavioral activation/inhibition systems, emotion dysregulation difficulties, and selective attention. The results revealed that parentless adolescents exhibited significantly higher levels of behavioral activation/inhibition scores, emotion regulation difficulties, and impaired selective attention. These findings suggest that the absence of parents during the early years of life may have detrimental effects on behavioral inhibition and activation systems, emotional regulation abilities, and selective attention capabilities. The implications of these findings are further discussed.

The Behavioral Inhibition System and Engagement With, and Influence By, COVID-19 and Election-Based Misinformation.

The negative impact of misinformation on public discourse and public safety is increasingly a focus of attention. From the COVID-19 pandemic to national elections, exposure to misinformation has been linked to conflicting perceptions of social, economic, and political issues, which has been found to lead to polarization, radicalization, and acts of violence at the individual and group level. While a large body of research has emerged examining the development and spread of misinformation, little has been done to examine the human processes of being exposed to, and influenced by, misinformation material online. This article uses reinforcement sensitivity theory to examine the effect of individual differences in the Behavioral Inhibition System (BIS) on the behavioral and cognitive intentions to engage in violence after exposure to misinformation online. Using an online panel sample (Mechanical Turk), and a behavioral study that involved exposure to, and interaction with, misinformation, this study found that trait BIS score impacted how much individuals engaged with misinformation, as well as their ensuing activism and radicalism toward the narratives that were depicted. This study identified that engagement with misinformation impacted intentions for activism and radicalism, as did trait BIS. However, these effects were present for both misinformation and correct information conditions. These findings highlight the importance of BIS-related processes and raise important questions about the degree to which we need to think about online influence as a general process versus specific processes that directly relate to the effect of misinformation.

Youth Dating Violence, Behavioral Sensitivity, and Emotional Intelligence: A Mediation Analysis.

Intimate partner violence is a multidimensional phenomenon encompassing psychological, physical, and sexual components. Violence in young couples is common in our society. This kind of violence is usually bidirectional, which adds to its complexity. This study aimed to explore how victimization (in three dimensions: non-abuse, technical mistreatment, and mistreatment) and perpetration (in two dimensions: non-perpetrator and perpetrator) are related to the BIS (Behavioral Inhibition System)/BAS (Behavioral Approach System), and it also evaluated if the dimensions of emotional intelligence (EI) (emotional attention, clarity, and regulation) mediate this relationship. Violence was evaluated in 272 young volunteer participants, as well as BIS/BAS behavioral sensitivity and perceived emotional intelligence. The correlations between these variables were analyzed, and a mediation analysis was also conducted. The results show that victimization (of the sexual and coercive type) was associated with less BAS activation, while victimization (of the sexual, humiliation, and detachment types) was associated with less BIS activity. All types of victimization were associated with less EI, specifically with less emotional clarity. Aggression (of the sexual, humiliation, detachment, and coercion types) was related to lower BAS and higher BIS sensitivity. Detachment aggression was associated with low emotional clarity. In conclusion, relationships between victimization and perpetration are evidenced in terms of BIS/BAS sensitivity and EI. Specifically, the dimension of EI emotional clarity acts as a mediator of BIS activation in victims of detachment.

Reduced reward responsiveness in treatment resistant depression of middle-aged adults: Association with carotid artery stiffness and tetrahydrobiopterin.

Nearly one third of the population diagnosed with major depressive disorder (MDD) fail to respond to two or more antidepressant drugs of adequate dose and duration. This necessitates identification of confounding psychological and physiological factors that could contribute to treatment resistant depression (TRD). The present longitudinal study investigated the influence of behavioural inhibition system (BIS) and behavioural approach system (BAS) in treatment resistance. Further, the association of depression severity with physiological factors contributing to arterial stiffness was also investigated. Baseline data was acquired from 101 middle-aged (36-56 years) patients on immediate diagnosis with MDD using DSM-V criteria. Follow ups were conducted at 06 months and 12 months during treatment. Psychological assessment battery at baseline and follow ups comprised of Hamilton depression rating (HAM-D) for depression severity, WHODAS-2 and BIS-BAS score. Atherosclerosis and central arterial stiffness were measured by intima-media thickness of internal carotid artery and brachial-ankle pulse wave velocity. Physiological factors influencing central vascular function viz., body-mass index, estimated glomerular filtration rate, HbA1c, central systolic and diastolic blood pressure, heart rate and tetrahydrobiopterin were also investigated. Our results show lower reward responsiveness (BAS-RR) and higher BIS scores in TRD patients along with differentially higher intima-media thickness of left internal carotid artery. Higher depression severity at all stages of the study was correlated with lower tetrahydrobiopterin and BAS-RR scores. We, therefore, suggest that vascular depression resulting due to increased intima-media thickness of left carotid artery and lower tetrahydrobiopterin could be contributing factors for treatment resistance in middle-aged MDD patients.

Exploring behavioral systems of the reinforcement sensitivity theory in people with epilepsy: A cross-sectional study

ObjectivesAlthough epilepsy has previously been associated with behavioral changes, no previous study has utilized the behavioral models of the reinforcement sensitivity theory (RST) to investigate the impact of epilepsy on behavior. Therefore, the objective of this cross-sectional study is to examine the potential relationship between epilepsy and the neurobehavioral systems of the RST. MethodsUsing the Reinforcement Sensitivity Theory–Personality Questionnaire (RST-PQ), this cross-sectional study assessed the behavioral systems of the RST in a sample of 27 epilepsy patients and 27 age- and gender-matched healthy individuals. The RST-PQ was designed to assess the different behavioral systems of the RST. The behavioral approach system (BAS) is responsible of the approach behavior, in high values related to risk seeking and addictive behavior and in low values well related to depression. The behavioral inhibition system (BIS) is well related to anxiety in high levels, and the fight flight freeze system (FFFS) is responsible for the avoidance behavior. ResultsAfter adjusting for age, no significant differences were found in demographic information (gender and marital status) between the general population and epilepsy patients. Gender distribution was similar, with 55.6% females in both groups. Marital status also showed no significant difference, with 74% single in the control group and 63% in the epilepsy group. Significant differences were observed in the behavioral systems of the RST. The epilepsy group had higher scores compared with the control group in several areas. BAS reward activity had a median score of 23 in the epilepsy group and 21 in the control group (p = 0.001). BAS goal drive persistence (p = 0.04), BAS impulsivity (p = 0.014), FFFS (p = 0.002), and BIS (median score of 77 in the epilepsy group and 66 in the control group) also showed significant differences, with p = 0.001. These significant differences remained consistent before and after matching the control group, indicating their robustness. The only exception was BAS reward activity, which did not show a significant difference after matching, with p = 0.106 and p = 0.051 before and after matching, respectively. ConclusionsThe study suggests a potential positive association between epilepsy and the BIS, potentially mediated by the hippocampus. The relationship between epilepsy and the BAS, as well as the FFFS, may also be influenced by the BIS. These findings have clinical implications, but further research is needed to confirm these relationships.

Dispositional mindfulness and BIS/BAS up-close: can the self-regulation of people be seen in the eyes?

Pigmentation in animal models is related to behavioral regulation and development, suggesting that both may belong to the same biological system. However, such models are poorly documented in humans. The current study explored personality and group differences in self-regulation among healthy subjects and their specific eye structures (contraction furrows and pigment spots). Three objectives were proposed: to analyze statistical differences in dispositional mindfulness (DM), behavioral inhibition system (BIS), and behavioral approach system (BAS) among subjects with a specific iris type of contraction furrows and pigment spots. The study sample consisted of 194 university students. One month after taking photographs of their eyes, the students completed the online scales of DM, BIS, and BAS. DM was negatively related to pigment spots (rs = -0.193; p < 0.01). Cluster analysis of the iris structures converged at a four-cluster solution. The cluster types 2 (absence of pigment spots and contraction furrows extending 8/10 of iris circle or more) and 3 (one or more pigment spots and contraction furrows extending 8/10 of iris circle or more) significantly differed in DM with a small effect size (F = 3.37; p = 0.021; η2 = 0.051). Participants with contraction furrows (8/10 or more circle extent) and without pigment spots had a significantly higher DM than those with pigment spots. No significant differences existed among the iris types in BIS/BAS. Future research directions are suggested.

Enhanced Punishment Responses in Patients With Schizophrenia: An Event-Related Potential Study.

It is well known that abnormal reward processing is a characteristic feature of various psychopathologies including schizophrenia. Reduced reward anticipation has been suggested as a core symptom of schizophrenia. The Monetary Incentive Delay Task (MID) is frequently used to detect reward anticipation. The present study aims to evaluate the amplitude and latency of event-related potential (ERP) P300 in patients with schizophrenia (SCH) compared to healthy controls during the MID task. Twenty patients with SCH and 21 demographically matched healthy controls (HC) were included in the study. ERP P300 amplitude and latency values were compared between groups using an MID task in which reward and loss cues were presented. Relations between P300 and clinical facets were investigated in the patient group. SCH group had enhanced mean P300 amplitudes and delayed peak latency in the punishment condition compared with HC. These higher responses were also associated with negative symptoms. SCH group showed altered reward processing as being more sensitive to loss of reward conditions as firstly evidenced by electrophysiological methods, possibly due to abnormality in various systems including social withdrawal, social defeat, and behavioral inhibition system.

Exploring Response Inhibition, the Behavioral Inhibition System and Possible Sex Differences in Athletes and Non-Athletes.

The objective of this study was to revisit the question concerning whether athletes are better than non-athletes at fundamental cognitive abilities, such as inhibitory control, in addition to also focusing on motivational dispositions and possible sex differences. Adding the latter could be crucial since both inhibitory control and motivational dispositions, such as approach and avoidance, are central to goal-directed behavior. This study's sample was composed of 93 participants (40 males): 29 biathletes; 30 alpine skiers; and 34 non-athletes. A non-sport-specific stop-signal task was used for the assessment of inhibitory control in terms of response inhibition, and the motivational dispositions were assessed with the BIS/BAS scales. The results showed that there were no differences between the two different sports or non-athletes with regard to response inhibition. However, females showed significantly slower response inhibition than males (p = 0.018) and scored significantly higher on the trait variable BIS (p < 0.001). The results from this study suggest that it might be meaningful to explore the contribution of sex differences and motivational dispositions on response inhibition in conjunction with different types of sports.

The effectiveness of cognitive behavioral therapy on behavioral inhibition and self-efficacy in children with specific learning disorders

Introduction: Specific learning disorder is one of the most important school-age disorders, and about 2-10% of children suffer from this disorder. Aim: The research was conducted with the aim of determining the effectiveness of cognitive behavioral therapy on behavioral inhibition and self-efficacy in children with specific learning disorders. Method: The research method was a semi-experimental type of pre-test and post-test with a control group. The statistical population of the research includes all elementary school girls aged 10 to 12 years who referred to the center of learning disorders in Babol city in 2021 (207 people), of which 30 people were selected by the available method and randomly in two experimental groups and controls were replaced. To collect data, Hoffmann (1984) Go/no-go Test (behavioral inhibition) and Morris Self-efficacy Questionnaire (2001) were used. The cognitive behavioral therapy program was implemented in 10 sessions of 45 minutes based on Seiler's model (2008) only on the experimental group. The data was analyzed using multivariate analysis of covariance (MANCOVA) with SPSS software version 18. Results: The results showed that there is a significant difference between the pre-test and post-test scores of the experimental and control groups in behavioral inhibition and self-efficacy in children with specific learning disorders (P&lt;0.01). In general, cognitive behavioral therapy is effective on behavioral inhibition and self-efficacy in children with specific learning disorders (P&lt;0.01). Conclusion: According to the results of this research, paying attention to the role of cognitive behavioral therapy in creating changes in the behavioral inhibition system and self-efficacy has important therapeutic implications. Therefore, paying attention to the role of cognitive behavioral therapy in making changes in the behavioral inhibition system and self-efficacy has important therapeutic implications.

Does Social Media Exposure Shape Consumer Response in the Form of Panic Buying?

This study took an effort to analyse the impact of social media exposure on the panic buying behaviour of people towards health and personal care products during COVID-19 times. The study also analyses the mediating role of anxiety between social media exposure and panic buying. This study attempts to explain the connection between social media exposure, anxiety, and panic buying using the social proof theory, the S–O–R model, and the behavioural inhibition system theory. The study includes a sample of 433 people. The data was collected from 24 items structured questionnaire distributed online. A total of 433 responses were collected online. The relationship between variables was analysed through structural equation modelling using Smart PLS-3. The results revealed that there is a direct effect of social media exposure on panic buying but when anxiety mediates the relationship between media and panic buying then a condition of partial mediation was observed. The result suggests that social media exposure directly affects panic buying among customers but it also affects generating anxiety among the customer. The study contributes by exploring the relationship between social media exposure, anxiety and panic buying. This study has a practical implication towards policymaking and the functioning of appropriate social media communication during an unstructured and disastrous situation.

Association of polymorphisms rs4680 of the Catechol-O-Methyltransferase gene and rs6265 of the brain derived neurotrophic factor gene with the behavioral inhibition and behavioral activation systems

The Behavioral Inhibition System (BIS) comprises limbic circuitry implicated in avoidance behaviors. Its increased activation has been identified as a risk factor for anxiety and depressive disorders. In addition, both Catechol-O-Methyltransferase (COMT) and Brain Derived Neurotrophic Factor (BDNF) have been postulated as candidate genes that constitute a vulnerability for the onset of anxiety and depressive disorders. The aim of this study was to evaluate the possible association between the rs4680 polymorphism of the COMT gene and the rs6265 polymorphism of the BDNF gene with the BIS and the Behavioral Activation System (BAS) in a population sample from Colombia. Genetic information was obtained by extracting DNA from blood samples of 80 participants and using Taqman probes designed for each polymorphism. In addition, participants completed a BIS/BAS scale in order to establish a neuropsychological classification. The frequency of the Met allele of the BDNF gene was greater in the group with BIS sensitivity compared to the group with BAS sensitivity. On the contrary, the frequency of the Met allele of the COMT gen did not show a significant association with the BIS. The rs6265 polymorphism of BDNF gene is associated with the BIS which in turn constitutes a risk factor for anxiety and depression.

The reinforcement sensitivity theory affects questionnaire (RST-AQ). A validation study of a new scale targeting affects related to anxiety, approach motivation and fear

This paper presents the RST-AQ, a 22-item scale to measure the affective states related to the three motivational systems postulated by Reinforcement Sensitivity theory (RST-AQ): the Behavioral approach system (BAS), Behavioral inhibition system (BIS), and the Fight-Flight-Freeze system (FFFS). The three subscales are internally consistent. Results show an overall support for construct validity of our RST-AQ measure. The correlations of the RST-AQ subscales with other measures demonstrate a good convergent and divergent validity with regard to the subscales of BAS and BIS. The RTS-AQ Scale provides researcher with the first instrument to measures the affective states of the RST theory.

The influence of the behavioural inhibition system on the development of PTSD-like symptoms after presentation of a traumatic film in healthy subjects

ABSTRACT Background: The Behavioural Inhibition System (BIS) as a neural system controlling motivation and behaviour, has previously been linked to multiple mental disorders, including Post-traumatic Stress Disorder (PTSD). BIS-sensitivity could increase the likelihood of PTSD development after trauma. However, previous studies have largely measured BIS-sensitivity retrospectively (i.e. after trauma, or even after onset of PTSD). Objective: The study aims to confirm the relationship between BIS-sensitivity prior to trauma and PTSD symptoms. Method: After assessment of BIS-sensitivity, N = 119 healthy participants watched a film with visually disturbing material. After 72 h, participants completed a questionnaire on PTSD-related symptoms (PCL-5). Results: In a multiple linear regression model, BIS-sensitivity significantly predicted PTSD symptoms, even after controlling for the decrease in mood, as well as for participants’ age and sex, two factors that had previously been shown to influence BIS-sensitivity. Conclusions: This is the first study to measure BIS-sensitivity before the occurrence of the (experimental) trauma and strengthens its role as a potential pre-traumatic risk factor.

Polish Validation of the Spontaneous Use of Imagery Scale (SUIS): Psychometric Characteristics and Relationships with Risk Propensity

In three studies, we developed the Polish version of the Spontaneous Use of Imagery Scale (SUIS), which measures individual differences in people's spontaneous use of mental imagery in everyday situations. The SUIS-PL consists of nine items with very good internal consistency and validity. For example, it shows a moderate correlation with the vividness of mental images and with temperamental traits related to the Behavioral Inhibition System (BIS) and the Behavioral Approach System (BAS). We also investigated the relationship between the SUIS-PL and measures of risk perception and willingness to take risks, showing the possible applicability of the scale in this context. Interestingly, we found that people with higher scores in the SUIS-PL were generally more willing to take risks, suggesting that they may spontaneously imagine positive, rather than negative, aspects of risky situations.

The Behavioral Inhibition System as a Mediator between Child Sexual Abuse and Perceived Pornography Addiction in Adulthood

Worldwide, an estimated 12.7% of children have experienced child sexual abuse (CSA). CSA can lead to mental health, emotional, and behavioral consequences that often persist into adulthood such as depression, post-traumatic stress disorder, suicidal ideation, and maladaptive sexual functioning (e.g. sexual avoidance, compulsivity). Research suggests that CSA may lead to unhealthy pornography use, a form of maladaptive sexual functioning, in adulthood, though the psychological pathways governing this relationship are unexplored. In this study, 182 United States-based individuals (mean age 36.637 [SD = 11.333] years, 51.648% men) were surveyed using Amazon MTurk regarding CSA history and perceived cyberpornography addiction. Participants also completed the Reinforcement Sensitivity Theory Personality Questionnaire (RST-PQ). We found that individuals who experienced CSA reported higher perceived cyberpornography addiction scores. Serial mediation model results indicated that the behavioral inhibition system (BIS) mediated the relationship between CSA and perceived cyberpornography addiction. The BIS is a dimension of the RST-PQ which resolves conflicts between the behavioral activation system (coordinates approach behaviors) and the flight-fight-freeze system (coordinates retreat behaviors) and is associated with trait anxiety. These findings contribute to the literature on the costs of CSA and identifies BIS sensitivity as a psychological system that can be targeted in therapeutic settings to reduce maladaptive engagement with pornography by CSA survivors.

Attachment, motivational systems and anorexia nervosa: A systematic review and proposed framework for eating disorders.

There is a direct association between patients with insecure attachment style (IAS), behavioural inhibition (BIS) and behavioural activation (BAS) motivational systems, and anorexia nervosa (AN). However, the possible direct relationships between these three variables have not been studied. The main objective of this study is to analyse the relationship between these variables and propose a framework for analysing and understanding these relationships. A systematic review was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, searching the following terms: 'anorexia', 'attachment' and those related to motivational systems. The final search was limited to publications in English dated between 2014-2022 for 'anorexia and attachment' and 2010-2022 for 'anorexia and BIS/BAS'. Of the 587 articles retrieved, 30 were included in this study for the textual data analysis of the relationship between anorexia and attachment (17), anorexia and motivational systems (10) and anorexia, attachment and motivational systems (3). An association between avoidant IAS, AN and hypersensitivity to punishment of the BIS was observed in the analysis. A relationship was also observed with hyperreinforcement sensitivity of the BAS. After reviewing the articles, a possible relationship between the three factors, along with other mediating factors, was found. AN is directly related to the avoidant IAS and to BIS. Similarly, bulimia nervosa (BN) was directly related with anxious IAS and BAS. However, contradictions were found in the BN-BAS relationship. This study proposes a framework for analysing and understanding these relationships.
