Test-retest reliability, agreement and construct validity of the International Physical Activity Questionnaire short-form (IPAQ-sf) in people with COPD
Publication . Flora, Sofia; Marques, Alda; Hipólito, Nádia; Morais, Nuno; Silva, Cândida G.; Januário, Filipa; Rodrigues, Fatima; Carreira, Bruno P.; Cruz, Joana
Introduction: This study assessed the test-retest reliability/agreement and construct validity of the International Physical Activity Questionnaire short-form (IPAQ-sf) in patients with chronic obstructive pulmonary disease (COPD). It also explored differences in its validity according to age, sex and GOLD airflow obstruction levels.
Methods: 62 participants (68 ± 8 years, 53 males, FEV1 51 ± 23%pred) completed the Portuguese IPAQ-sf, wore an accelerometer for 7 days and completed a second IPAQ-sf. Test-retest reliability/agreement was assessed with Intraclass Correlation Coefficient (ICC2,1), 95% Limits of Agreement (LoA), standard error of measurement (SEM) and minimal detectable change (MDC95) for continuous variables, and percentage of agreement (%agreement) for categories ("active"/"inactive"). Validity was assessed with 95% LoA and Spearman's correlations (ρ) between IPAQ-sf 2 (METs-min/week, time in vigorous [VPA], moderate PA [MPA] and walking) and accelerometry (time in MVPA, VPA, MPA and step counts) for continuous variables; %agreement, Cohen's kappa, and sensitivity specificity and±predictive values for categories. Correlations were also performed for age, sex and GOLD airflow obstruction grades.
Results: Reliability was good (ICC2,1 = 0.707) with wide LoA (-6446-6409 METs-min/week). SEM and MDC95 were 1840 and 4971 METs-min/week, respectively. %agreement between the two IPAQ-sf was 84% (kappa = 0.660). Positive, moderate and significant correlations were found between IPAQ-sf and accelerometry (0.396 ≤ ρ ≤ 0.527, p < 0.001), except for VPA (p > 0.05). The strongest correlations were found in age (<65 years) and male (0.466 ≤ ρ ≤ 0.653, p < 0.05). %agreement between tools was 65% (kappa = 0.313), with high sensitivity (0.830) but low specificity (0.500).
Conclusions: The IPAQ-sf seems valid to be used in COPD but caution on its widespread use is recommended as its accuracy may be limited.
A integração da família nos cuidados de enfermagem: perspetiva de enfermeiros e estudantes de enfermagem
Publication . Frade, João Manuel; Graça Henriques, Carolina Miguel; Frade, F.
Enquadramento: A pertinência da integração das famílias nos cuidados de enfermagem permite a
promoção, manutenção e recuperação da saúde das famílias.
Objetivos: Identificar e descrever a perspetiva dos enfermeiros e estudantes de enfermagem sobre a
integração das famílias nos cuidados de enfermagem.
Metodologia: Estudo inferencial, transversal, numa população de enfermeiros e estudantes de en fermagem. Foi aplicada a escala Families Importance in Nursing Care – Nurses Attitudes (FINC-NA).
Resultados: Amostra constituída por 164 indivíduos, nos quais 71 eram profissionais e 93 estudantes.
A média da importância atribuída à família foi maior nos estudantes de enfermagem relativamente
aos enfermeiros, sendo a diferença entre os dois grupos significativa. Na análise de regressão linear
univariada as variáveis: Idade, Anos de experiência profissional e Formação na área da família parecem
estar associadas à importância atribuída à família.
Conclusão: Os estudantes atribuem maior importância à integração da família do que os enfermeiros.
As variáveis Idade, Anos de exercício profissional e Formação na área da família, nos enfermeiros,
associam-se a uma maior importância da integração da família.
Impact on the Mental and Physical Health of the Portuguese Population during the COVID-19 Confinement

Confinement of the population has been one of the measures implemented by different
governments to address the COVID-19 health crisis, and it has led to social isolation together with a
disruption of daily activities. The aim of the study is to analyze psychological distress during the
COVID-19 pandemic in Portugal. During the quarantine, a cross-sectional study was carried out on a
sample of 2120 subjects over 18 years of age, resident and born in Portugal. Data were collected using
a self-developed questionnaire that considered socio-demographic variables, physical symptoms,
health conditions, and history of contact with COVID-19, as well as psychological alterations. The
General Health Questionnaire (GHQ-12) was also included. Univariate and bivariate statistical
analyses were performed. Predictive capacity was studied using logistic regression models. The
results showed a higher percentage of individuals presenting psychological distress (57.2.0%), with
a higher percentage identified among women (79.0%), and in people with a higher educational
level (bachelor’s + master’s and doctorate) (75.8%). The predictor variables with the greatest weight
were sex, educational level (graduation, master’s, and doctorate), living with children or under
16 years of age, presence of symptoms, and quarantine in the last 14 days for having symptoms.
Good self-assessment of health and working at home appear to be protective against psychological
distress. These results highlight the impact of the COVID-19 pandemic on psychological distress and
provide an opportunity to consider the need to implement specific multidisciplinary public health
and mental health interventions in this pandemic situation.
