Validation and cultural adaptation of Russian version of KOOS-Child questionnaire

Introduction. In our research 100 patients (51 male and 49 female) aged below 18 were assessed with the following knee problems: meniscal, anterior cruciate ligament, posterior cruciate ligament tears, mediopatellar plica syndrome, osteochondritis dissecans. Aim: validation and cultural adaptation English version of KOOS-Child questionnaire for Russian language children and adolescent patients. Also, for using in N.N. Priorov National Medical Research Center of Traumatology and Orthopedics and other medical hospitals of Russian Federation. Materials and methods. KOOS-Child has been translated in Russian language by orthopedist who is advanced in English and by professional medical translator. For control group we used Lysholm knee score. After all procedures statistical analysis was used. It consists of 3 stages: general data analysis, validation checking of questionnaire, checking objectivity and relevance of results. Conclusions. Cronbachs alpha test score shows up very high-level consistency of the questions (0,959). Questions have high discriminatory power and results of assessment are objective and adequate. Methods of statistical analysis showed up that questionnaire can be use in practice by orthopedist.

Indicators of Pre-Suicidal State of Minors in the Internet Space

The article aims to describe potential indicators of pre-suicidal state of minors manifesting in online-behavior that were revealed in the empirical study which involved 43 respondents aged 13-15 (M=14.19). The subjects for the study were selected among the teenagers who had responded to our advertisement messages published in various groups on the VKontakte social network. The following methodologies were used: UCLA Loneliness Scale (version 3) (D. Russell, L. A. Peplau, M. Ferguson); Beck Hopelessness Inventory; WHO-5 Well-being Index (1998); Cognitive Errors in Online Communication (I.S. Luchinkina); Sentence Completion for Events from the Past Test (SCEPT) (F.Raes et al.); Individual Typological Child Questionnaire (L.N. Sobchik). The data obtained lead to conclude about the characteristics of the profile related to presence of a distinct pre-suicidal condition: a tendency towards increase in the proportion between the number of subscriptions where suicide is mentioned (including those associated with corresponding emotions, as well communities collecting suicide-related art) and the total number of subscriptions. The number of comments on one's page is inversely proportional to the severity of one's pre-suicidal condition.

Komunikacja matki z dzieckiem w okresie prenatalnym

The aim of this paper is to present theories, current research on the forms and importance of a mother’s communication with her child in a prenatal period, and discuss the results of own research in this area. In the research, the Communication with a Prenatal Child Questionnaire was used which measures six forms of prenatal communication. Prenatal communication is significant for both a mother and a child in her womb. Thanks to prenatal communication the mother can explore more consciously the challenges of pregnancy which are preparatory tasks for the role of a parent and the child develops better. The mother learns how to express her feelings non-verbally through empathy, facial expressions, touch, synchrony, and intuition. After childbirth, she can use the forms of communication from the prenatal period.

Validity of Items Assessing Self-Reported Number of Breaks in Sitting Time among Children and Adolescents

Background: Sedentary behaviour guidelines recommend that individuals should regularly break up sitting time. Accurately monitoring such breaks is needed to inform guidelines concerning how regularly to break up sitting time and to evaluate intervention effects. We investigated the concurrent validity of three “UP4FUN child questionnaire” items assessing the number of breaks in sitting time among children and adolescents. Methods: Fifty-seven children and adolescents self-reported number of breaks from sitting taken at school, while watching TV, and during other screen time activities. Participants also wore an activPAL monitor (PAL Technologies, Glasgow, UK) to objectively assess the number of sitting time breaks (frequency/hour) during the school period and the school-free period (which was divided in the periods “after school” and “during the evening”). Concurrent validity was assessed using Spearman rank correlations. Results: Self-reported number of breaks/hour at school showed good concurrent validity (ρ = 0.676). Results were moderate to good for self-reported number of breaks/hour while watching TV (ρ range for different periods: 0.482 to 0.536) and moderate for self-reported number of breaks/hour in total screen time (ρ range for different periods: 0.377 to 0.468). Poor concurrent validity was found for self-reported number of breaks/hour during other screen time activities (ρ range for different periods: 0.157 to 0.274). Conclusions: Only the questionnaire items about number of breaks at school and while watching TV appear to be acceptable for further use in research focussing on breaks in prolonged sitting among children and adolescents.

Associations between Parental and Friend Social Support and Children’s Physical Activity and Time Spent outside Playing

The purpose of this study was to examine the structural validity of a parent and a child questionnaire that assessed parental and friends’ influences on children’s physical activity and investigate the associations between the derived factors, physical activity, and time spent outside. Children (N=154, mean age = 11.7) and 144 of their parents completed questionnaires assessing parental and friends’ influences on children’s physical activity. Children wore a pedometer for six days. Exploratory factor analyses revealed four factors for the parental and five for the child’s questionnaire that explained 66.71% and 63.85% of the variance, respectively. Five factors were significantly associated with physical activity and five significantly associated with time spent outside. Higher correlations were revealed between “general friend support,” “friends’ activity norms,” and physical activity (r=0.343and 0.333 resp.,p<0.001) and between “general friend support” and time spent outside (r=0.460,p<0.001). Obtaining information relating to parental and friends’ influences on physical activity from both parents and children may provide a more complete picture of influences. Parents and friends seem to influence children’s physical activity behavior and time spent outside, but friends’ influences may have a stronger impact on children’s behaviors.
