Cognitive Control Processes and Defense Mechanisms That Influence Aggressive Reactions: Toward an Integration of Socio-Cognitive and Psychodynamic Models of Aggression

Impact of Defense Mechanism Styles on Disease Progression in Patients with Gastrointestinal Cancer: Focusing on Clinical Staging

BACKGROUND

The escalating incidence of cancer and the concurrent rise in mental health issues necessitate investigation into the potential for psychological factors to impede timely and effective treatment. This study examines the association between defense mechanism styles and disease progression, specifically focusing on clinical staging, in patients diagnosed with gastrointestinal (GI) cancer.

METHODS

Employing a descriptive correlational design, the study recruited 205 patients with GI cancer admitted to Javad Al-Aeme Hospital in Kerman, Iran, during the year 2022. Convenience sampling was utilized for participant selection. Data collection instruments included the Defense Style Questionnaire-40 (DSQ-40) and patients' documented clinical stage information. Correlation coefficients and ordinal logistic regression were employed for data analysis.

RESULTS

Over half of 205 GI cancer patients were female (53.2%). The majority were married (85.8%) with an average age of 53.86 ± 8.21 years. Nearly a quarter (23.9%) were in disease stage 1, with similar proportions in stages 2 (25.4%), 3 (27.3%), and 4 (23.4%). The findings revealed a significant inverse correlation between mature defense mechanism styles and clinical stage (r =  - 0.55, p < 0.001), indicating that patients who employed more adaptive defense mechanisms had lower-stage cancer. Conversely, a significant positive correlation was observed between immature defense mechanism styles and clinical stage (r =  - 0.49, p < 0.001), suggesting that patients who relied on less effective defense mechanisms had more advanced-stage cancer. However, no significant association was found between neurotic defense mechanism styles and clinical stage (r =  - 0.12, p = 0.079).

CONCLUSIONS

This study provides preliminary evidence that defense mechanism styles are associated with disease progression in patients with GI cancer. Mature defense mechanisms may promote slower disease progression, while immature defense mechanisms may contribute to more advanced disease stages. Further research is needed to confirm these findings and develop interventions to improve psychological well-being in this patient population.

Aggressive behaviors predict greater intraindividual reaction time variability in children: Evidence from cross-lagged panel models

Deficits in attentional control or inhibitory control are distinct features of childhood aggressive behaviors. Lower attentional control or inhibitory control is considered to predict more aggressive behaviors, while few studies have documented the possible predictive effects of aggressive behaviors on attentional control or inhibitory control. The present study examined the bidirectional relations between aggressive behaviors and both inhibitory control and attentional control in 169 Chinese primary school children (75 girls, Mage  = 7.15, SDage  = 0.33), annually for 3 years starting at age 7. The No-go accuracy on a Go/No-go task was used as the index of inhibitory control, and the intraindividual reaction time variability (IIRTV) of correct Go trials indicated attentional control. The aggressive behaviors subscale of the child behavior checklist-Chinese version was used to assess the children's aggressive behaviors. The results demonstrated a significant and stable predictive effect of previous aggressive behaviors on subsequent attentional control, with more aggressive behaviors predicting greater IIRTV at both the between-child and within-child levels. No significant effects of inhibitory control or attentional control on aggressive behaviors or sex-specific patterns were found. The findings suggest the negative impact of childhood aggressive behaviors on attentional control and underscore the importance of early prevention and intervention for childhood aggressive behaviors.
