The purpose of this qualitative study of families where a parent has cancer was to explore ways of informing the child of the parent's illness, how the child perceives the parent's emotional state, how the child copes with the parent's illness, and how this coping relates to the parent's coping and concerns for the child. Twenty-one children from 15 families and their parents were interviewed. In 13 families the mother was ill, in two the father. Children were aware of the facts of the illness, but there was limited emotional communication between the generations. The children were very observant of both the ill and the healthy parent's emotional condition. The children's observations and expressions led us to identify five coping strategies the younger generation used: Helping others, parentification, distraction, keeping it in the head, and wishful thinking. Both adaptive and destructive examples of parentification were found. Communication patterns and parental coping seemed to be highly related to the child's coping repertoire. Even though most children seemed to manage rather well, all children were strongly affected by the illness. The 'healthiest' adaptation related to factors within the family system, which has implications for the provision of help.

BACKGROUND: This study aimed to evaluate prevalence and risk factors for emotional and behavioral problems in dependent children of cancer patients using a multinational research design. METHODS: The

Background: The differential susceptibly hypothesis suggests that certain genetic variants moderate the effects of both negative and positive environments on mental health and may therefore be important predictors of response to psychological treatments. Nevertheless, the identification of such variants has so far been limited to preselected candidate genes. In this study we extended the differential susceptibility hypothesis from a candidate gene to a genome-wide approach to test whether a polygenic score of environmental sensitivity predicted response to cognitive behavioural therapy (CBT) in children with anxiety disorders. Methods: We identified variants associated with environmental sensitivity using a novel method in which within-pair variability in emotional problems in 1,026 monozygotic twin pairs was examined as a function of the pairs' genotype. We created a polygenic score of environmental sensitivity based on the whole-genome findings and tested the score as a moderator of parenting on emotional problems in 1,406 children and response to individual, group and brief parent-led CBT in 973 children with anxiety disorders. Results: The polygenic score significantly moderated the effects of parenting on emotional problems and the effects of treatment. Individuals with a high score responded significantly better to individual CBT than group CBT or brief parent-led CBT (remission rates: 70.9, 55.5 and 41.6%, respectively). Conclusions: Pending successful replication, our results should be considered exploratory. Nevertheless, if replicated, they suggest that individuals with the greatest environmental sensitivity may be more likely to develop emotional problems in adverse environments but also benefit more from the most intensive types of treatment.

Twenty-four families participated in counselling for families with a parent with cancer (24 mothers, 17 fathers, and 34 children). Parents who received counselling were significantly more depressed before the counselling than a nonrandomized control group who did not receive counselling, but participated in another part of the project. For the parents, there was a significant decrease in depression and increase in family functioning scores from before to after the intervention. For the children, a significant pre- to post-decrease in depression scores was found. Changes in depression and family functioning were significantly correlated with the degree of counselling contentment. Reasons for seeking counselling were insecurity in relation to the children, problems with communication, high level of conflict, and change of roles. A number of themes appeared when parents and children described what they gained from the counselling: Confirmation in being a 'good-enough' parent, more understanding of emotions and reactions of other family members, more sense of intimacy and cohesion within the family, and normalization of own feelings.
