- Contributo de fatores individuais, sociais e ambientais para a decisão de prosseguir uma gravidez não planeada na adolescência: Um estudo caracterizador da realidade portuguesaPublication . Pires, R; Pereira, J; Araújo Pedrosa, A; Vilar, D; Vicente, L; Canavarro, MC
- Ecological Contexts in Adolescent Pregnancy: The Role of Individual, Sociodemographic, Familial and Relational Variables in Understanding Risk of Occurrence and Adjustment PatternsPublication . Araújo-Pedrosa, A; Pires, R; Carvalho, P; Canavarro, MC; Dattilio, FAdolescent pregnancy appears today as an intricate tapestry where different dimensions interact. In our study we examined the associations between individual, sociodemographic, familial, and relational variables and their impact on the occurrence of pregnancy and adolescents’ adjustment to it. Participants were Portuguese pregnant and non-pregnant adolescents (N = 833). Ecological contexts were characterized, and individual and relational adjustment (depressive symptoms and quality of life; perceived quality of relationship with significant others—parents, romantic partner and friends) were evaluated. Differences between the ecologies of adolescents in both groups were identified. Familial and relational variables were significantly associated with both the risk of pregnancy and more difficulties in adjustment. Implications for preventive intervention are discussed.

- Gravidez e parentalidade na adolescência: perspetivas teóricasPublication . Canavarro, MC; Araújo-Pedrosa, AEmpirical research grounded on ecological perspectives challenge the view of adolescent motherhood has necessarily having deleterious consequences to the later development of young mothers and their offspring; nonetheless it is still irrefutable that the occurrence of an early pregnancy may amplify previous vulnerabilities, making it more difficult for the adolescent mother and her child to develop along a favorable path. The present work reviews some of the current theoretical perspectives on this subject, looking to highlight the importance of understanding not only individual or family variables of the young girls who get pregnant, but also relational, social, cultural, legal and political contexts in which they develop. Knowledge of these multiple dimensions and of their complex interactions is crucial to design more specific and effective preventive interventions.
- The importance of family context in alcoholismPublication . Vaz-Serra, A; Canavarro, MC; Ramalheira, CIn the present study, 56 chronic alcoholics were compared with 56 controls with no excessive drinking habits, all of them male. The drinking habits of their parents were studied, as were parental rearing, dyadic relations with the spouses, attachment to significant people, and the education they gave to their own children. It was noted that the alcoholics' parents had heavier drinking habits and could have acted as learning models. As regards the other characteristics, the dyadic cohesion, the global score of the education received from the father and the personal style of criticism/rejection in the education of their own children were underlined
- Relational and reproductive trajectories leading to adolescent pregnancy in Portugal: a national and regional characterizationPublication . Pires, R; Pereira, J; Pedrosa, AA; Bombas, T; Vilar, D; Vicente, L; Canavarro, MCINTRODUCTION: The current study aimed to describe the relational and reproductive trajectories leading to adolescent pregnancy in Portugal, and to explore whether there were differences in this process according to adolescents' place of residence. MATERIAL AND METHODS: Data were collected between 2008 and 2013 in 42 public health services using a self-report questionnaire developed by the researchers. The sample consisted of a nationally representative group of pregnant adolescents (n = 459). RESULTS: Regardless of having had one (59.91%) or multiple sexual partners (40.09%), the majority of adolescents became pregnant in a romantic relationship, using contraception at the time of the conception and knowing the contraceptive failure which led to pregnancy (39.22%). In some regions other trajectories were highly prevalent, reflecting options such as planning the pregnancy (Alentejo Region/ Azores Islands), not using contraception (Centro Region/Madeira Islands) or using it incorrectly, without identifying the contraceptive failure (Madeira Islands). On average, romantic relationships were longer than 19 months and adolescents' partners were older than themselves (> 4 years) and no longer in school (75.16%); these results were particularly significant when the pregnancy was planned. DISCUSSION: The knowledge gained in this study shows that prevention efforts must be targeted according to the adolescents' needs in each region and should include high-risk male groups. CONCLUSION: Our results may enable more efficient health policies to prevent adolescent pregnancy in different country regions and support educators and health care providers on sexual education and family planning efforts.
- The Portuguese version of the Body Image Scale (BIS): psychometric properties in a sample of breast cancer patientsPublication . Moreira, H; Silva, S; Marques, A; Canavarro, MCPURPOSE: The aim of this study was to analyse the psychometric properties of the Portuguese version of the body image scale (BIS; Hopwood, P., Fletcher, I., Lee, A., Al Ghazal, S., 2001. A body image scale for use with cancer patients. European Journal of Cancer, 37, 189-197). This is a brief and psychometric robust measure of body image for use with cancer patients, independently of age, cancer type, treatment or stage of the disease and it was developed in collaboration with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Study Group. METHOD: The sample is comprised of 173 Portuguese postoperative breast cancer patients that completed a battery of measures that included the BIS and other scales of body image and quality of life, in order to explore its construct validity. RESULTS: The Portuguese version of BIS confirmed the original unidimensional structure and demonstrated adequate internal consistency, both in the global sample (alpha=.93) as in surgical subgroups (mastectomy=.92 and breast-conserving surgery=.93). Evidence for the construct validity was provided through moderate to largely sized correlations between the BIS and other related measures. In further support of its discriminant validity, significant differences in BIS scores were found between women who underwent mastectomy and those who underwent breast-conserving surgery, with the former presenting higher scores. Age and time since diagnosis were not associated with BIS scores. CONCLUSIONS: The Portuguese BIS proved to be a reliable and valid measure of body image concerns in a sample of breast cancer patients, allowing a brief and comprehensive assessment, both on clinical and research settings.
