Emotional isolation and negative life experiences have been found to influence suicidal and self-harming thoughts among isolated and reclusive young people.

In a paper titled "Factors Influencing Suicidal and Self-Harming Thoughts Among Isolated and Reclusive Youth," published in Volume 46, Number 2 of Health and Welfare Policy Forum, an academic journal by the Korea Institute for Health and Social Affairs, a research team led by Kang Min-hee and Jeon Jong-seol from the Ewha Womans University Graduate School of Social Welfare presented these findings based on an analysis of 486 individuals selected from the 2002 Seoul City survey on isolated and reclusive youth.

The types of isolated and reclusive youth among the study subjects were distributed as follows: the dependent type with a relatively low level of isolation (32.9%), the reclusive type marked by prominent physical isolation (21.6%), the frustrated type combining economic vulnerability and emotional isolation (22.8%), and the relationship-severed type characterized by the weakening or severance of social networks (22.8%).

There were 227 males and 259 females, making females slightly more numerous, and the average age was 30.4 years.

Regarding final educational attainment, 121 individuals had a high school education or below, and 365 had a college degree or above, with college graduates or higher being about three times more numerous than those with high school education or below.

The socio-economic level subjectively perceived by the individuals (scored from 1 to 5) averaged 2.23 points.

By household type, multi-person households accounted for 359 individuals (73.9%) and single-person households for 127 individuals (26.1%).

Among these, the lower the subjective socio-economic level, the higher the level of suicidal and self-harming thoughts, and single-person households tended to show higher levels than multi-person households.

Variables such as emotional isolation, physical isolation, negative experiences before adulthood, and negative life experiences after adulthood were also found to have a significant impact on suicidal and self-harming thoughts.

Among the variables, emotional isolation and negative experiences before adulthood showed a higher correlation with suicidal and self-harming thoughts.

Meanwhile, the level of suicidal and self-harming thoughts varied by type among isolated and reclusive youth. Specifically, the levels of suicidal and self-harming thoughts were higher in the reclusive type (average 1.91) and the frustrated type (1.88) compared to the dependent type (0.49) and the relationship-severed type (0.25).

Emotional isolation, physical isolation, and negative life experiences before and after adulthood were also prominently high in the reclusive and frustrated types.

The research team stated, "The study results imply that approaches simply increasing the frequency of going out or social contact are insufficient to alleviate the suicide risk of isolated and reclusive youth," adding, "Support policies need to shift beyond interventions focused on increasing physical activity toward restoring emotional support and the quality of relationships."
