Illness unpredictability and psychosocial adjustment of adolescent and young adults impacted by parental cancer: the mediating role of unmet needs.

PURPOSE: Given the large number of adolescents and young adults (AYAs) impacted by parental cancer and the potential for negative psychosocial outcomes in this vulnerable population, this study examined the mediating role of offspring unmet needs with regard to parental cancer and the relation between AYAs psychosocial adjustment and perceived illness unpredictability. METHODS: A total of 113 AYAs (aged 11-24 years) living with a parent diagnosed with cancer completed a questionnaire assessing illness unpredictability, offspring unmet needs, and psychosocial adjustment (i.e., health-related quality of life and internalizing problems). RESULTS: Higher offspring unmet needs were associated with lower health-related quality of life (r = -0.24**) and higher internalizing problems (r = 0.21*). Offspring unmet needs mediated the relation between illness unpredictability and health-related quality of life (standardized indirect effect = -0.100* [-0.183, -0.018]) but not internalizing problems (standardized indirect effect = 0.067 [-0.015, 0.148]). In particular, higher illness unpredictability was related to higher unmet needs (ß = 0.351**) which, in turn, predicted lower health-related quality of life (ß = -0.286**). CONCLUSION: These findings identify offspring unmet needs and illness unpredictability as implicated in AYAs positive psychosocial adjustment to parental cancer. Given that AYAs are at greater risk of elevated psychosocial difficulties, interventions should target offspring unmet needs and perception of illness unpredictability to mitigate the adverse effects of parental cancer.

The need for a behavioural science focus in research on mental health and mental disorders.

Psychology as a science offers an enormous diversity of theories, principles, and methodological approaches to understand mental health, abnormal functions and behaviours and mental disorders. A selected overview of the scope, current topics as well as strength and gaps in Psychological Science may help to depict the advances needed to inform future research agendas specifically on mental health and mental disorders. From an integrative psychological perspective, most maladaptive health behaviours and mental disorders can be conceptualized as the result of developmental dysfunctions of psychological functions and processes as well as neurobiological and genetic processes that interact with the environment. The paper presents and discusses an integrative translational model, linking basic and experimental research with clinical research as well as population-based prospective-longitudinal studies. This model provides a conceptual framework to identify how individual vulnerabilities interact with environment over time, and promote critical behaviours that might act as proximal risk factors for ill-health and mental disorders. Within the models framework, such improved knowledge is also expected to better delineate targeted preventive and therapeutic interventions that prevent further escalation in early stages before the full disorder and further complications thereof develop. In contrast to conventional "personalized medicine" that typically targets individual (genetic) variation of patients who already have developed a disease to improve medical treatment, the proposed framework model, linked to a concerted funding programme of the "Science of Behaviour Change", carries the promise of improved diagnosis, treatment and prevention of health-risk behaviour constellations as well as mental disorders.

Psychological predictors of mortality in heart transplanted patients: a prospective, 6-year follow-up study.

BACKGROUND: Some reports suggest a link between poor psychological adjustment to heart transplantation and an increased risk of subsequent adverse clinical outcome. Despite its prognostic and therapeutic implications, this issue is still lacking adequate empirical studies. We prospectively tested the predictive value of a complete set of psychiatric and psychological variables, collected with both self-rating and observer-based instruments at midterm after heart transplantation, on the subsequent 6-year survival status. METHODS: Ninety-five heart transplanted patients underwent the structured clinical interview for Diagnostic and Statistical Manual of Mental Disorders-4th Edition and the structured interview for Diagnostic Criteria for Psychosomatic Research and filled three questionnaires assessing the dimensions of psychological distress, quality of life, and psychological well-being. Demographic characteristics and several clinical parameters were also collected. A 6-year follow-up survival was performed. RESULTS: Analyses of survival showed that hostility, depression, purpose in life, the occurrence of at least one cardiac event, chronic renal insufficiency, diabetes, number of drug prescriptions, a New York Heart Association (NYHA) class more than or equal to II, and ischemic origin of the cardiopathy significantly predicted subsequent survival duration. When multivariate analyses were performed, high levels of hostility and the presence of diabetes resulted the independent predictors of survival status. CONCLUSIONS: These findings point out the predictive role of specific components of psychological adjustment to heart transplantation and pose the basis for the evaluation of whether the provision of pharmacologic and psychotherapeutic interventions, aimed at reducing the empirically identified psychological risk factors, may result in a better long-term outcome.

Relationship between psychiatric disorders and physical status during the course of a heart transplantation program: a prospective, longitudinal study.

BACKGROUND: Evidence of a lack of relationship between psychiatric disorders and physical status during a heart transplantation (HT) program would configure mental well-being as an independent endpoint deserving specific interventions. METHODS: We report a prospective, longitudinal study on patients (n=127) undergoing HT in order to investigate the relationship between psychiatric disorders and physical status. RESULTS: At pre-HT evaluation, at least one psychiatric disorder according to the DSM-IV diagnoses was present in 27 patients (21%); the prevalence of psychiatric disorders was not related (p > or = 0.150) to physical status (assessed by clinical, electrocardiographic, echocardiographic, and hemodynamic parameters). At post-HT evaluation 1 year after HT, all clinical-instrumental parameters significantly improved (p < or = 0.016), but not the prevalence of psychiatric disorders, which were diagnosed in 34 patients (p = 0.016 vs pre-HT). CONCLUSIONS: During the HT program, no significant relationship exists between physical status and prevalence of psychiatric disorders, which increases after the operation. This finding indicates the need for the mandatory provision of adequate psychological support during all of the phases of the HT experience.

Psychological assessment in cardiac rehabilitation.

BACKGROUND: While there has been an upsurge of interest in the psychiatric correlates of myocardial infarction, little is known about the presence of psychological distress in the setting of cardiac rehabilitation. METHODS: A consecutive series of 61 patients with recent myocardial infarction who participated in a cardiac rehabilitation program was evaluated by means of both observer-rated (DSM and DCPR) and self-rated (Psychosocial Index) methods. A follow-up of this patient population was undertaken (median = 2 years). Survival analysis was used to characterize the clinical course of patients. RESULTS: Twenty percent of patients had a DSM-IV diagnosis (in half of the cases minor depression). An additional 30% of patients presented with a DCPR cluster, such as type A behavior and irritable mood. Only high levels of self-perceived stressful life circumstances and psychological distress approached statistical significance as a psychological risk factor for cardiovascular events after myocardial infarction. CONCLUSIONS: Psychological evaluation of patients undergoing cardiac rehabilitation needs to incorporate both clinical (DSM) and subclinical (DCPR) methods of classification. Type A behavior was present in about a quarter of patients and can be studied in specific subgroups of cardiovascular patients defined by DCPR.
