Teens who live with only one of their parents are more likely to show ‘delinquent’ behaviours – even if there’s a step-parent in the home, a new study says.
Academics in Sweden studied surveys of 14 and 15-year-olds in a variety living arrangements, including living with both parents, a single parent and a step-parent.
Some of the adolescents had engaged in various offences, ranging in seriousness from graffiti to robbing someone and carrying a knife as weapon.
Teens living in single-father, single-mother, father-stepmother and mother-stepfather households reported more delinquency than those living with both their parents, the academics found.
The study authors have stressed that if a teen is living with only one of their biological parents is does not necessarily mean they are delinquents.
As they studied results from Swedish teens of quite a narrow age range, further research may be needed.
Teenagers who live in single-parent families are more likely to show ‘delinquent’ behaviours such as shoplifting and graffiti, the study says
The new study was published this week in the open-access journal PLOS One by Robert Svensson and Björn Johnson at Malmö University, Sweden.
‘This study shows that it is important to move on to the use of more detailed categorisations of family structure in relation to delinquency,’ they say in their paper.
‘We need to increase our knowledge about the group of adolescents that moves between parents.’
Previous studies have found that not living with both parents is positively associated with delinquency behaviours.
However, these have been ‘highly simplified’, in that they only compared living with both parents versus not living with both parents, for instance.
For the new study, the researchers took into account the wider living arrangements of teens who did not live with both of their parents.
They made the distinction between teens living in either ‘symmetrical’ or ‘asymmetrical’ family arrangements.
Symmetrical family arrangements are those where both parents are single, or both parents have a new partner.
Meanwhile, ‘asymmetrical’ family arrangements are those where either the mother or the father, but not both, have a new partner.
For the study, behaviours defined as delinquent ranged in seriousness from graffiti to robbing someone and carrying a knife as weapon
Researchers used data from four cross-sectional surveys carried out between 2016 and 2019 in southern Sweden, comprising a total of 3,838 teens aged 14 to 15.
The surveys were conducted at 17 secondary schools in eight small municipalities in the county of Skåne, Sweden’s southermost county, with a population of around 1.4 million.
Data included self-reported information on nine delinquent behaviors – incluidng shoplifting, graffiti, robbing someone and carrying a knife when out the house – as well as detailed family structure.
Compared to adolescents living with both their mother and their father, delinquent behaviour was more common among those living with a single father, a single mother, a father and stepmother, or a mother and stepfather.
Among all participants, teens in symmetrical families – where parents live separately and share custody but are both single or both have new partners – generally reported lower levels of delinquency than those in asymmetrical families.
However, the experts also found that many of the associations between family structure and delinquency declined when adjusted for data on parental attachment and monitoring.
Researchers admit they did not prove causality in their study – in other words, they did not demonstrate that certain family structures cause delinquency and other don’t.
Another limitation is that the study sample came from teens in just a single Swedish country; further research would ideally include a much bigger sample.
Overall, the authors conclude that categorising family structure more precisely can shed light on the contributing factors of delinquency.
