Disruptive mood and emotional conflict resolution in adolescent children of parents with recurrent depression or bipolar disorder and healthy controls

Plain English Summary

Background and study aims
Mood disorders are psychological disorders which cause the elevation or lowering of a person’s mood, the most common examples of which are depression (major depressive disorder or unipolar depression) and bipolar disorder. It has been widely shown that mood disorders in parents may have an effect on the mental health of their children, increasing the risk of developing mental disorders. Examples of such are Severe Mood Dysregulation Disorder (SMDD) and Disruptive Mood Dysregulation Disorder (DMDD), which are characterised as severe and persistent irritability.
It has also been suggested that these children would not perform as well as children of healthy parents in conflict resolution tasks.
This study aims to find whether adolescent children of parents suffering from unipolar or bipolar disorder are more likely to show signs of mental disorders (such as DMDD and SMDD) compared to adolescent children of healthy parents. Additionally, the study aims to test how adolescent children of parents suffering from unipolar or bipolar disorder perform at conflict resolution tests than adolescent children of healthy parents.

Who can participate?
Adolescent children of adults with depression or bipolar disorder and adolescent children of healthy adults (control group)

What does the study involve?
Parents complete a number of questionnaires in order to assess their mental state. The adolescent offspring of both healthy parents and parents with unipolar/bipolar disorder complete further questionnaires to find out how many are affected by SMDD and DMDD. They are then shown a series of pictures of faces showing different emotions, as well as shapes and letters in various colours. The time it takes for them to respond to these pictures and letters is then measured.

What are the possible benefits and risks of participating?
The main benefit of pariticipating for both parents and adolescents will be knowledge gained on disorders and their effects.There are no notable risks of participating.

Scientific title

Rates of psychopathology including Disruptive Mood Dysregulation Disorder and emotional conflict resolution among adolescent children of parents with recurrent Major Depressive Disorder versus those with Bipolar Disorder and matched healthy controls

Acronym

Study hypothesis

1.That Severe Mood Dysregulation Disorder (SMDD)/Disruptive Mood Dysregulation Disorder (DMDD) diagnoses would be significantly more common among adolescent offspring of parents with mood disorders as a group compared to healthy controls.
2. That Severe Mood Dysregulation Disorder (SMDD)/Disruptive Mood Dysregulation Disorder (DMDD) diagnoses would be related with emotional conflict resolution as reflected in response latencies and errors in an emotional stroop paradigm.

Condition

Disruptive Mood Dysregulation Disorder

Intervention

Parents' psychological status is evaluated with Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). All parents will then complete SCL-90R, State-Trait Anxiety Inventory- Trait Version, General Functioning Subtest of the Family Assessment Scale, and Childhood Trauma Questionnaire- 28.
The psychological status of adolescents are evaluated with the Kiddie-Sads-Present and Lifetime Version (K-SADS-PL). Additionally SMDD Module as well as DSM-5 criteria for DMDD will be screened. They also complete Children's Depression Inventory, State-Trait Anxiety Inventory- Trait Version, Childhood Trauma Questionnaire- 28. Neuropsychological evaluations are Stroop Color Word Test- TBAG Form and Emotional Stroop (word-face) paradigm. The visual component of the emotional stroop was formed from pictures in the NIMH Child Emotional Faces Picture Set (NIMH-ChEFS) and the verbal component from TUDADEN (Affective Norms of Turkish Words). Also, the pubertal status will be evaluated with self-report via Turkish translation of the Carskadon Puberty Scale.

Publication and dissemination plan

Dr. Topal will complete and defend her Dissertation in February 2016. Thereafter, a complete version of the Dissertation in Turkish will be stored in the Electronic Dissertation Database of Council of Higher Education of Turkey (https://tez.yok.gov.tr/UlusalTezMerkezi/ or https://tez.yok.gov.tr/UlusalTezMerkezi/giris.jsp (webpage in English)). We plan to present the results of primary and secondary analyses in 2016 as new research posters and to complete the final manuscript and submit it to a peer reviewed journal at the end of 2016 at the latest.
Post-hoc analyses will focus on the relationships between general psychopathology/ trait anxiety in family members, family functioning, traumatic experiences and DMDD symptoms in offspring. They will be conducted in 2016 and will be presented/disseminated in 2017. Please note that we will also define a priori hypotheses before undertaking any of the post-hoc analyses (e.g. trait anxiety in parents will be positively correlated with trait anxiety in offspring and negatively correlated with family functioning, traumatic experiences in parents will be positively correlated with threat bias in offspring etc.).
