まとめ
ほとんどの子どもは 自分を傷つける考えや行動 (SITB) を一貫して報告しません 幼少期に共通するこの不一致は 未熟性から生じ,若者の自殺リスク評価に影響する可能性があります.
科学分野:
- 児童・青少年精神科
- 発達心理学
- 臨床心理学
背景:
- 自己傷害思考と行動 (SITBs) は,縦断的な研究でしばしば不一致に報告されています.
- 子どもにおけるこの報告の不一致に関するデータは限られている.
- 若者の報告パターンを理解することは リスクの正確な評価に不可欠です
研究 の 目的:
- 子供のSITB報告の不一致の流行,相関,および発達変化を調査する.
- 幼児期の不一致を報告する要因を特定する.
主な方法:
- Adolescent Brain Cognitive Development (ABCD) 研究 (ベースライン,第1年,第2年) のデータを活用した.
- コンピュータ化された臨床面接で毎年評価された生涯SITB.
- 2つのコホート (N=1,350とN=1,086) で1年間の報告の一貫性を計算した.
- 不一致な報告のモデルと相関する物流回帰を用いた.
主要な成果:
- 1年目では,SITBを報告した子供の67% - 80%が,SITBを承認しなかった.
- 臨床症状の重度が低く,年齢が若く,神経認知機能が低下すると,不一致性が高かった.
- 自殺以外の自傷行為に関する報告の不一致は,BL-Y1 (80%) からY1-Y2 (73%) にわずかに減少した.
結論:
- SITBの不一致の報告は,幼児期に標準です.
- この現象は,臨床的重症性,神経認知性,および発達不成熟に関連している可能性があります.
- 若者の自殺リスクの評価を改善するために,不一致な報告の背後にあるメカニズム (例えば,忘却,再概念化,非開示) を理解するためにさらなる研究が必要です.

Longitudinal Research
12.5K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Revisionist Views of Adolescent and Adult Cognition
99
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...
