Abstract [en]

Background

The current study aimed at exploring adolescents’ experiences of online sexual contacts leading to online sexual abuse by a perpetrator whom the victim had first met online. Associations with socio demographic background, experience of abuse, relation to parents, health and risk behaviors were studied.

Methods

The participants were a representative national sample of 5175 students in the third year of the Swedish high school Swedish (M age = 17.97). Analyses included bivariate statistics and stepwise multiple logistic regression models.

Results

In total 330 (5.8%) adolescents had gotten to know someone during the preceding 12 months for the purpose of engaging in some kind of sexual activity online. Thirty-two (9.7%) of those, the index group, had felt that they had been persuaded, pressed or coerced on at least one occasion. Sexual interaction under pressure was seen as constituting sexual abuse. These adolescent victims of online sexual abuse, the index group, did not differ with respect to socio-demographic background from the adolescents without this experience, the reference group. The index group had significantly more prior experiences of different kind of abuse, indicating that they belong to a polyvictimized group. More frequent risk behavior, poorer psychological health, poorer relationships with parents and lower self-esteem also characterized the index group. Online sexual abuse, without experiences of offline abuse, was associated with a poorer psychological health, at least at the same level as offline sexual abuse only.

Conclusions

The study made clear the importance of viewing online sexual abuse as a serious form of sexual abuse. Professionals meeting these children need to focus not only on their psychological health such as symptoms of trauma and depression but also need to screen them for online behavior, online abuse and other forms of previous abuse.

Abstract [en]

Differences and similarities were studied in the functions of two different self-injurious behaviors (SIB): nonsuicidal self-injury (NSSI) and sex as self-injury (SASI). Based on type of SIB reported, adolescents were classified in one of three groups: NSSI only (n = 910), SASI only (n = 41), and both NSSI and SASI (n = 76). There was support for functional equivalence in the two forms of SIB, with automatic functions being most commonly endorsed in all three groups. There were also functional differences, with adolescents in the SASI only group reporting more social influence functions than those with NSSI only. Adolescents reporting both NSSI and SASI endorsed the highest number of functions for both behaviors. Clinical implications are discussed, emphasizing the need for emotion regulation skills.

Abstract [en]

In addition to money or other compensation, other motives for selling sex may be important in a welfare country such as Sweden. The aim of this study was to carry out an exploratory investigation of adolescents motives for selling sex in a population-based survey in Sweden. A total of 5839 adolescents from the third year of Swedish high school, mean age 18.0 years, participated in the study. The response rate was 59.7% and 51 students (0.9%) reported having sold sex. Exploratory factor analysis and hierarchical cluster analysis were used to identify groups of adolescents according to underlying motives for selling sex. Further analyses were carried out for characteristics of selling sex and risk factors. Three groups of adolescents were categorized according to their motives for selling sex: Adolescents reporting; 1) Emotional reasons, being at a greater risk of sexual abuse, using sex as a means of self-injury and having a non-heterosexual orientation. 2) Material but no Emotional reasons, who more often receive money as compensation and selling sex to a person over 25 years of age, and 3) Pleasure or no underlying motive for selling sex reported, who were mostly heterosexual males selling sex to a person under 25 years of age, the buyer was not known from the Internet, the reward was seldom money and this group was less exposed to penetrative sexual abuse or using sex as a means of self-injury. In conclusion, adolescents selling sex are a heterogeneous group in regard to underlying motives.

Abstract [en]

Introduction. – The Trauma Symptom Inventory-2 (TSI-2) is a broad-spectrum assessment instrumentdesigned to identify symptoms that can appear in the aftermath of potentially traumatic experiences.

Objective. – This study aimed to evaluate the external and internal validity of this newly reconstructedinstrument.Method. – In total, 696 individuals participated in the study, including 83 psychiatric outpatients. Participants answered the TSI-2, together with a trauma history questionnaire, and other questionnairesassumed to correlate with the different scales included in the TSI-2.

Results. – Validity was evaluated by correlations between the TSI-2 and the other instruments and bythe differences between clinical and non-clinical populations. Reliability was calculated by testinginternal consistency and test-re-test reliability. A confirmatory factor analysis (CFA) was computed totest the postulated four-factor structure. Cronbach’s alpha was found to be good and ranged froma = .77 to .91 and test-retest reliability was strong. Strong to satisfactory correlations were foundbetween the TSI-2 and the other instruments. The student sample scored significantly lower than theclinical group on all clinical scales. Sensitivity and specificity were calculated with different cut-offscores.

Conclusion. – Despite the CFA demonstrating a questionably good model of fit, most of the scales provedto be sound and the TSI-2 could be recommended as a broad-spectrum assessment instrument.

Abstract [en]

Sex as self-injury has become a concept in Swedish society; however it is a largely unexplored area of research, not yet conceptualized and far from accepted in the research field. The use of sex as a way of affect regulation is known in the literature and has, in interviews with young women who sell sex, been compared to direct self-injury, such as cutting or burning the skin. The aim of this study was to investigate the self-reported frequency of sex as self-injury and the association to sociodemographic factors, sexual orientation, voluntary sexual experiences, sexual risk-taking behaviors, sexual, physical and mental abuse, trauma symptoms, healthcare for psychiatric disorders and non-suicidal self-injury.

AimThis Swedish study compared reading skills between seven-year-old children with a very low birthweight (VLBW) and controls with a normal birthweight, exploring associations between reading variables and cognition, parent-rated behaviour, perinatal factors and family factors. MethodsWe studied 51 VLBW children, with no major neurodevelopmental impairments and attending their first year at a regular school, and compared them with the 51 sex- and age-matched controls. The test battery, carried out at 7.80.4years of age, included reading skills, the Wechsler Intelligence Scale for Children - III and the Child Behaviour Checklist. ResultsVery low birthweight children with a mean birthweight of 1105g (+/- 291g) and a gestational age of 28.8 (+/- 2.2) weeks scored significantly lower in all reading subtests and cognition and demonstrated more behavioural problems than normal birthweight controls. We also found significant associations between poor vocabulary, combined with attention problems, and phonological awareness, rapid naming and spelling control. Perinatal factors had no association with reading function, and socio-economic factors had very few. ConclusionVery low birthweight children demonstrated deficits in all reading domains and had poorer cognition and more behavioural problems at the age of seven, with reading ability related to vocabulary and attention.

Abstract [sv]

TSI-2 är ett självrapporteringsformulär som mäter posttraumatisk stress och relaterade symptom och beteenden. TSI-2 syftar till att identifiera symptom som kvarstår hos individen efter en eller flera svåra livshändelser. Mer specifikt är instrumentet avsett att användas för vuxna som har upplevt traumatiska händelser i livet såsom exempelvis fysiska eller sexuella övergrepp, olyckor, katastrofhändelser, traumatiska förluster, dödsfall av närstående, medicinska trauman eller bevittnat hot och våld. TSI-2 mäter ett brett spektrum av traumatiska symptom och lämpar sig framförallt för screening men kan också användas för att utvärdera effekter av psykoterapeutiska interventioner.

TSI-2 består av 136 påståenden som ger resultat på:

Två validitetsskalor

Underrapportering eller förnekande av symptom, samt en skala gällande överrapportering av traumarelaterade symptom.

Fyra faktorer

Självförvirring, Posttraumatisk stress, Externalisering och Somatisering.

Tolv kliniska skalor

Ångestfylld spändhet, Depression, Ilska, Invaderande återupplevande, Undvikande, Dissociation, Somatisk upptagenhet, Sexuella svårigheter, Självmordsbenägenhet, Osäker anknytning, Skadad självkänsla, Spänningsreducerande beteende.

Den svenska versionen av TSI-2 är standardiserad och normerad vid Linköpings universitet och Uppsala universitet under åren 2012-2014. Normgruppen består av sammanlagt 693 individer i åldrarna 18-65 år. En klinisk grupp med 83 individer ingår också i valideringen av den svenska versionen av TSI-2. Utvecklingsarbetet och den svenska versionens psykometriska egenskaper beskrivs i manualen, som även innehåller anvisningar för administrering, poängsättning och tolkning samt köns- och åldersspecifika normtabeller.

Abstract [sv]

Avdelningen för barn och ungdomspsykiatri vid Linköpings universitet fick i uppdrag av Stiftelsen Allmänna Barnhuset att tillsammans med Statistiska Centralbyrån (SCB) genomföra en kvantitativ studie bland unga i gymnasieskolans år 3. Avtalets huvudfokus var att samla in kunskap om ungdomars sexualitet, erfarenheter av övergrepp, sexuell exponering, sexuell exponering via digitala medier i enlighet med Regeringsbeslut S2013/8825/FST. Inom ramen för uppdraget skulle samråd med Ungdomsstyrelsen och Folkhälsomyndigheten tas och undersökningen skulle ske i samarbete med Lunds Universitet.

Samtidigt med detta gavs ett uppdrag från socialförvaltnings utvecklingsenhet i Stockholms stad, om en komplettering genom en vidgad datainsamling i Stockholms stad. Detta uppdrag skulle framför allt fokusera på barn och ungdomar i sexhandel/prostitution samt de som skadar sig själva med sex. Då de två studierna använt en identisk enkät och det i analyserna av materialet visat sig vara väldigt små skillnader mellan de två dataseten så redovisas i denna rapport det sammanlagda materialet.

Detta är den tredje stora nationella studien på området om ungdomars sexualitet och utsatthet för sexuella övergrepp och sexuell exploatering. Den första studien Ungdomars sexualitet –attityder och erfarenheter (Svedin &Priebe, 2004) var ett uppdrag inom ramen för den statliga utredningen Sexuell exploatering av barn i Sverige (SOU, 2004:71). Den andra undersökningen Unga, sex och internet (Svedin & Priebe, 2009) genomfördes på uppdrag av Ungdomsstyrelsen i avsikt att genomföra en kvantitativ studie bland unga i gymnasieskolans år 3 samt bland Riksförbundet för homosexuella, bisexuella och transpersoners rättigheters (RFSL) medlemmar i relevant ålder. Dessa två studier, vars vetenskapliga publikationer presenteras i bilaga 1, har inom centrala områden använt samma enkät vilket möjliggör en jämförelse med den aktuella studien men också att studera trender över tid. Att just kunna jämföra olika undersökningar med varandra och över tid är tämligen unikt vilket ofta rekommenderas från olika håll. Samtidigt som centrala frågeområden som t.ex. sexuella övergrepp och sexuell exploatering behållits så har andra områden bytts ut. I denna rapport är områden som själskadebeteende, sex som självskadebeteende, människohandel för sexuella syften samt mobbing nya (enkäten bilaga 2).

Abstract [en]

The study compared adolescents who alternate residences between their divorced parents with adolescents who live with both parents or with one divorced parent. Care was scored equally for adolescents with alternating residences and for those living with both biological parents but lower for adolescents living with a single parent. Overprotection showed the converse. Presence of psychiatric symptoms was equal for adolescents who alternate residences and for those living with both parents, but it was higher for those living with a single parent. Sense of coherence was noted to be higher among teens with alternating residences and teens living with both parents, but it was lower among those living with a single parent.

Abstract [en]

Background. There are still diverging results concerning the behaviour of children with very-low-birth-weight (VLBW) and they have been questioned to display different levels of stress hormone than normal-birth-weight (NBW) children. Aims. This study examined behaviour and the stress hormone cortisol in children with VLBW at the ages of 7 and 9 years compared with children with NBW. Results. Fifty-one VLBW and 50 NBW children were studied with the Child Behavior Checklist. Cortisol rhythm was measured through saliva samples three times a day for 2 days. VLBW children displayed more behavioural problems than NBW children, specifically social and attention problems, although still within normal ranges. They showed lower cortisol levels both at 7 and 9 years of age. No strong association between behaviour and cortisol levels was shown. Conclusion. VLBW children display more behaviour problems compared with NBW children but both groups score are within the normal range. Down-regulation of their hypothalamic-pituitary-adrenal (HPA) function in terms of lower cortisol levels is also noted.
