Assessment of motivating factors to follow a time-restricted eating dietary protocol

The number of clinical studies assessing the effects of time-restricted eating (TRE) has increased in recent years(1). The results of the studies conducted on humans demonstrate some health benefits, however, there is still a need to design larger and longer randomized clinical trials to prove the effectiveness and long-term benefits of these types of interventions(2). However, to ensure these health benefits, individuals need to be able to integrate its principles into their daily routines. This work aimed to associate daily habits with the potential adherence to different TRE protocols and to determine the factors that predict adherence to these protocols.A cross-sectional study was conducted using an online questionnaire based on a previous study(3), to assess the dietary and sleeping habits, daily routines and willingness to adhere to different windows of time-restricted eating in a sample of Portuguese adults. To analyze the associations between variables, the Spearman correlation coefficient and the Chi-Square test were calculated, and multiple linear regression was performed to identify the predictive factors. Statistical analysis was conducted on IBM SPSS Statistics version 29.0.130 responses were obtained (26% men, 74% women) with a mean age of 37.9±13.59 years old. On workdays, 60.0% of participants reported a daily eating window (the period between the first and last caloric intake) of 12h-14h, while on free days the highest percentage (41.5%) was between 10h12h. An inverse correlation was observed between age and willingness to adhere to a TRE protocol if there were health benefits (r=-0.356, p<0.001). Moderate correlations were also found between the availability to follow a TRE protocol on work days (r=0.538) and free days (r=0.598) and the potential health benefits of this type of intervention (p<0.001)). Associations were found between sex and potential adherence to the TRE protocol (χ2=10.644, df=2, p=0.005), with a tendency for more men not to adhere to a TRE protocol. There was also an association between body weight management and reducing the eating window by 1h-2h (χ² =24.883, df=12, p=0.015) and 2h-3h (χ²=22.367, df=12, p=0.034). The living situation, motivation for change, income, weight management, cooking knowledge, and working schedule were among the main factors predicting the willingness to adhere to TRE protocols (p<0.05).People’s willingness and motivation to adhere to TRE protocols outside the controlled environment of a clinical study depends on several factors. The results presented herein provide information that may be central when considering the translation of study results into nutritional practice and counselling.

Sociopolitical Trends and Attitudes Towards Transgender People: A Validation Study of the Transgender Knowledge, Attitudes, and Beliefs (T-KAB) Scale in a Portuguese Sample

Abstract Introduction Attitudes towards transgender and gender diverse (TGD) individuals are associated with discrimination against TGD people and underly TGD minority stress. Despite Portugal’s progressive legal framework, anti-trans interactions and discourse are reported. Nonetheless, studies on trans attitudes are still incipient in Portugal. The Transgender Knowledge, Attitudes, and Beliefs (T-KAB) scale is a psychometrically sound measure of transgender attitudes. However, its convergent validity with transphobia is yet to be tested, and its ability to study sociopolitical factors driving pro-trans attitudes is unexplored. Methods We explored the psychometric properties of the European Portuguese version of T-KAB in an online collected (February 2022 to May 2022) sample of Portuguese adults (N = 447), and tested differences (ANOVA; t-test) in T-KAB according to sociopolitical factors. Results Results from the Principal Axis Factoring and Parallel Analysis showed a two-factor measure of acceptance, comfort, and social tolerance towards trans people. Both factors presented an excellent internal consistency (α = .94 and α = .95) and were significantly associated with the Genderism and Transphobia Scale. Conclusions Results found that participants with a heterosexual orientation, less contact with TGD people, less educated, religious, and who endorsed a right-wing or conservative political ideology showed lower T-KAB scores. These results corroborate the psychometric validity of the T-KAB, as well as its ability to identify sociopolitical segments of the population according to their attitudes towards TGD people. Policy Implications This study informs future research on tailored interventions to increase transgender acceptance, comfort, and social tolerance in the general population.

Psychometric properties and further validation of the emergency reaction questionnaire in a sample of Portuguese adults

Emergencies and disasters are abrupt, unexpected, dangerous events often traumatic. Individuals differ in the way they respond to this kind of adverse experience, depending on varied factors. This study used the Emergency Reaction Questionnaire (ERQ) to assess defensive mechanisms, feelings, and thoughts during emergency and disaster-related situations. The main objective of the present study was to confirm the factor structure and provide further support to the validity of the ERQ on a Portuguese sample. Here we replicated previous findings in showing that people who are more prone to react in an organized way in emergencies tend to have lower anxiety levels and a greater tendency for sensation seeking. We also found that females score lower than males; that ERQ specific readiness scores slightly increase with age and people who have risky jobs or routinely engage in extreme sports scored higher on the ERQ scales (meaning they act more readily and organized in an emergency). The ERQ and its Portuguese version show to be a psychometrically sound and valid measurement of emergency behavior, able to assess individual differences in the way people perform during various emergencies, and can be used in future research and in practice for screening or measuring training efficiency.

Family Functioning in a Portuguese Sample of Adults during COVID-19: Does Hope Matter?

The purpose of this study was to explore the relationships between sociodemographic, clinical, and psychological variables and their contribution towards family functioning during the first wave of COVID-19 in Portugal. The COVID-19 pandemic was an overwhelming and stressful life event with social consequences that impacted family functioning and contributed to multilevel disruptions. The study used a cross-sectional design and included 110 participants (94 women), with a mean age of 35.71 (SD = 13.53). Participants answered self-report measures assessing family satisfaction, hope, psychological well-being, risk perception, and family functioning. Hope (pathways subscale) played a moderating role in the relationship between family satisfaction and family functioning. Family satisfaction and psychological well-being partially mediated the relationship between hope and family functioning. Clinical relevance and implications for further research are addressed. Intervention should focus on increasing psychological well-being and hope together with family satisfaction in order to promote family functioning. For those individuals struggling with COVID-19 issues, mental health interventions are paramount.

Mucua: Sensory analysis of the fruit of Adansonia digitata L. (Baobab) in natura

The mucua is the fruit of the embondeiro or baobab (Adansonia digitata L.) and originates from Africa. It has a high content of ascorbic acid and dietary fiber, along with antioxidant properties. The aim of this study was to test the acceptability of the mucua fruit in natura in a sample of Portuguese adults and test its intention to consume and availability to pay for this fruit. After providing the fruit, participants fulfilled a questionnaire for their socioeconomic characterization and tested their acceptability and willingness to pay for the fruit. The participatants in this study (n=53) were 20 years old, primarily female (80.8%), Portuguese (73.1%), and students (86.6%). The tasters considered the following aspects of the mucua fruit pleasant or very pleasant: global appreciation (49.2%), color (71.2%), shape (53.8%), flavor (40.4%), aroma (48.5%) and texture (44.2%). Approximately 30% of tasters would be willing or very willing to consume this fruit regularly and pay 3 €/ kg (62.9%). The mucua had good acceptance by the tasters, and the color, the form, and the global appreciation, were the attributes with the best scores on the acceptability test. In addition, they were willing to consume it regularly if they were available at an economically affordable price.

The Twenty Item Values Inventory (TwIVI) in Portuguese Adults: Factorial Structure, Internal Consistency, and Criterion-Related Validity

The Schwartz Model of Basic Values is an influential framework that describes what people find important and worth pursuing in life. The model proposes that ten human values are found cross-culturally, and so significant efforts have gone into empirically testing these claims. While instruments such as the Portrait Values Questionnaire-40 (PVQ-40) reliably discriminated the full set of theorized values, briefer versions have either suffered from a lack of construct validity (PVQ-21) or from not having been put through a rigorous statistical test of its underlying structure (Twenty Item Values Inventory [TwIVI]) via confirmatory factor analysis (CFA). The present study, using a Portuguese sample of adults (n = 524), is the first to examine the factorial structure of the TwIVI via CFA. We apply a magnifying glass approach by testing two separate models, each covering five values, which reflect the Growth and Self-protective dimensions. Moreover, we provide evidences that the TwIVI is reliable and capable of capturing the theorized quasi-circumplex structure, and the cross-cultural gender differences and relative hierarchical importance of values. Finally, we establish criterion-related validity, with values correlating with political identity and social and economic issues.

The portuguese version of the big three perfectionism scale – further validation with adults from the general population

IntroductionBoth original Big Three Perfectionism Scale (BTPS; Smith et al. 2016), and the Portuguese version validated with a sample of university students (Lino et al. 2018) evaluates three second-order factors (rigid, self-oriented and narcissistic perfectionism) and ten facets.ObjectivesTo confirm the BTPS three-factors-ten-dimensions’ structure in a sample of Portuguese adults from the general population.MethodsA sample of 467 adults (70.7% females; Mean age=38.44±12.27; range: 25-82) answered the BTPS Portuguese version and other validated perfectionism measures (Multidimensional Perfectionism Scales from Frost and Hewitt & Flett; Self-Presentation Perfectionism Scale). To study the temporal stability a sub-sample of 132 participants completed the BTPS again after approximately five weeks. SPSS and AMOS software was used.ResultsThe second order model presented an acceptable fit (X²/df=3.115; TLI=.811; CFI=.825; RMSEA=.067). There was also evidence of a general factor comprising all the 45 items (X²/df=3.127; TLI=.809; CFI=.823; [JA1] RMSEA=.068). The Cronbach alphas of the three factors ranged from a=.88 to a=.92; and facets had a>.70 showing a total of a=.94. Total and dimensional scores showed significant positive and moderate to high correlations with the other perfectionism measures and their test-retest correlation coefficients were r=.85 (p<0.001).ConclusionsThis study confirms the validity and reliability of the Portuguese BTPS underlying three-factors structure. Additionally, we found, for the first time, that BTPS can also be validly and reliably used to measure a global perfectionism construct. It is our intention to develop a shorter version the Portuguese BTPS in the near future.

Mediterranean Diet Adherence and Subjective Well-Being in a Sample of Portuguese Adults.

The Mediterranean diet (MD) and other lifestyle characteristics have been associated with well-being, a broad multiparameter concept that includes individual’s subjective assessment of their own well-being (SWB). Some studies have suggested that diet influences SWB, thus, this work aimed to add novel information on the association of MD and SWB in a sample of Portuguese adults. Data on sociodemographic, economic, lifestyle, diet, and SWB were collected through a self-filled online questionnaire. MD adherence was assessed by the Mediterranean Diet Adherence Screener (MEDAS) score. Results showed a moderate adherence to the MD in 490 Portuguese adults (mean MEDAS of 7.4 ± 2.1). A higher MD adherence was found to be significantly positively associated with women, employed individuals, a higher number of meals per day, and those with frequent contact with nature (p-value < 0.0025, using Bonferroni adjustment). As a novelty, this study divided the participants into low SWB, medium SWB, and medium to high SWB profiles (3.9 ± 1.0; 6.2 ± 1.0; 8.2 ± 1.3, respectively; p-value < 0.05), which reported significantly increasing MEDAS scores (6.5 ± 2.1; 7.3 ± 2.1; 7.8 ± 1.9; respectively, p-value < 0.05).

Knowledge and Myths about Palliative Care among the General Public and Health Care Professionals in Portugal.

Background: International research has shown that healthcare professionals (HCPs) and nonhealthcare professionals (NHCPs) are unaware of the goals and purposes of palliative care. This study evaluates the knowledge of palliative care among a sample of Portuguese adults and correlates their level of knowledge with age, gender, profession, and experience of family member’s palliative care. Method: A cross-sectional online survey was carried out on a sample of 152 HCPs and 440 NHCPs who completed an anonymous questionnaire of sociodemographic, family, and professional data, and an instrument of 26 dichotomous (true or false) questions focusing on palliative care goals and purposes. Results: The 592 participants had a mean age of 31.3 ± 11.1 years, and most were female. Statistically significant differences between statements considered as correct by HCPs and NHCPs were found in 24 statements; HCPs had the highest percentage of correct answers. The terms most frequently associated with palliative care mentioned by NHCPs were chronic and progressive disease (n = 76), while HCPs mostly mentioned quality-of-life promotion (n = 29). Women, the elderly, and HCPs had a higher level of knowledge regarding palliative care (p < 0.001). Conclusions: Results clearly show gaps in knowledge of palliative care, especially among NHCPs. An integrated approach is needed to inform and clarify the philosophy and goals of palliative care in different settings in order to improve knowledge.

Exploring Lifestyle Habits, Physical Activity, Anxiety and Basic Psychological Needs in a Sample of Portuguese Adults during COVID-19.

This cross-sectional study aimed to characterize the lifestyle habits, anxiety levels and basic psychological needs (BPN), in Portuguese adults during the Coronavirus Disease 2019 (COVID-19) pandemic, including a comparison between genders and age groups. In total, 1404 adults (36.4 ± 11.7 years; 69.6% female) answered sociodemographic data and three instruments: the International Physical Activity Questionnaire, the Basic Need General Satisfaction Scale and the State-Trait Anxiety Inventory. Males revealed higher values for the total energy expenditure (z = −2.26; p = 0.024; = 0.004) and for the level of satisfaction of competence (z = −2.62; p = 0.009; = 0.005). Females showed higher scores for the anxiety state (z = −7.87; p ≤ 0.001; = 0.044) and anxiety trait (z = −6.49; p ≤ 0.001; = 0.030). Regarding age, higher values for the anxiety trait (p ≤ 0.001; = 0.030) were found in the 18–34 years-old group compared to all the other age groups, also presenting significantly higher values of total energy expenditure (χ² = 13.93; p = 0.008; = 0.007) when compared to the 35–44 years-old group. Significant differences were observed between the 18–34 years-old group and the other age groups for the satisfaction of competence (χ² = 40.97; p ≤ 0.001; = 0.026), except for the >65 years-old group. Strategies for promoting well-being during periods of social isolation should consider the role of psychological dimensions and lifestyle habits according to the gender or age group.

Development of a Prototype-Based Scale for Assessing Saudade

Saudade is a psychological experience resulting from the absence of significant others or familiar places. Four studies were conducted in view of creating a measure of saudade derived from previous prototype analyses. Data from four samples were collected: two samples of Portuguese undergraduate students, one sample of Portuguese adults, and one sample of Portuguese adolescents. Through exploratory and confirmatory factor analyses, a three-factor latent structure of saudade was identified: Missing Close Others, Lack of Intimacy, and Longing for the Past. This three-factor structure was meaningfully associated with theoretically related constructs such as life satisfaction, negative affect, loneliness, love satisfaction, self-esteem, or neuroticism and was not associated with theoretically unrelated constructs such as tolerance or openness.

Socio-demographic factors associated with physical activity and sitting time patterns in adults: An analysis based on the Portuguese Food, Nutrition and Physical Activity Survey

ABSTRACT Physical activity (PA) and sedentary behaviours (SB) influence health. Since most people engage in different combinations of both behaviours every day, understanding the socio-demographic characteristics of adults with distinct PA and sitting time (ST) patterns is important to contribute to evidence-based planning of public health strategies. Data from a national survey on diet and activity behaviours (IAN-AF, 2015/16) including 1724 adults (50.5% women, 18–64 years) from a representative sample of Portuguese adults was used in this study. Participants were interviewed face-to-face, and the International Physical Activity Questionnaire (IPAQ) was used. Logistic regression examined the associations between socio-demographic factors each of the four-low/high PA-ST groups. PA low/high categories were defined as in IPAQ, while ST low/high categories were defined according to ST tertiles (≤180 min/day, ≥360 min/day). A ‘higher risk’ behaviour pattern (low PA/high ST) was present in 37.3% of the adults and was likely associated with a middle household income, and with having 12 or more years of education. The ‘lower risk’ (high PA/low ST) represented 26.6% of the sample and was likely associated with middle-aged adults and with having a lower educational level. Being male, young and highly educated was related to being physically active and spending large amounts of time in ST. Besides adding to the body of mixed evidence on this theme, the identification of the socio-demographic factors associated with each PA/ST pattern will permit national public health authorities to define policies and tailored actions to promote PA and reduce ST.

Subjective Well-being, Personality, and Loneliness as Correlates of Saudade: A Preliminary Study

AbstractSaudade is a psychological reaction to the absence of significant others or familiar places. The correlates of the experience of saudade were examined using a sample of Portuguese adults. Two hundred and twenty-seven participants of both genders, aged 20–65, were presented with (a) the Satisfaction with Life Scale (SWLS), (b) the Positive and Negative Affect Schedules (PANAS), (c) the brief Loneliness Scale (ULS-6), (d) the Neo Five-Factor Personality Inventory (NEO-FFI), and (e) an experience of saudade two-item scale. Experience of saudade was more often reported by females than by males, and positively correlated with negative affect, loneliness, and neuroticism.

Validation and invariance across age and gender for the Melbourne Decision-Making Questionnaire in a sample of Portuguese adults

AbstractThe personal pattern of coping with the stress associated with making decisions characterizes the way an individual makes choices and judgments. The Melbourne Decision Making Questionnaire (MDMQ) analyses these personal patterns and has been used across various cultures in order to assess four main strategies: vigilance, buck-passing, procrastination, and hypervigilance. We sought to adapt and validate a Portuguese version of the MDMQ. Our study was conducted with a sample of 523 Portuguese people aged 18 or older. The questionnaire retained the original four scales, which represent four different decisional patterns, showing good reliability and validity – concurrent as well as predictive – and invariance for gender and age. The coping pattern with the highest mean was vigilance, while procrastination had the lowest mean. In contrast to other studies of the MDMQ, our sample had a more diversified distribution of age. Young adults were less capable than older adults of managing stress when making decisions, due to their higher levels of buck-passing, hypervigilance, and procrastination. Vigilance showed stronger correlations to positive affect, satisfaction with life, and better decisional self-esteem, while the remaining scales were related to negative affect, reduced decisional self-esteem, and lower satisfaction with life. These decision-making styles are chosen depending on time constraints, pressure, or other contextual characteristics. These results suggest that individuals resort to more convenient patterns according to their situation, and that these patterns of decision-making can be trained, developed, and improved.

Cultural Adaptation and Psychometric Properties Assessment of the NOC Outcome "Cognition" in a Sample of Portuguese Adults With Mental Illness.

Cultural adaptation and psychometric properties assessment of the Nursing Outcomes Classification (NOC) outcome "Cognition" in a sample of Portuguese adults with mental illness. Methodological study. The final European Portuguese version of the NOC outcome "Cognition", consisting of 13 items, showed good psychometric properties. An exploratory factor analysis was performed from which only one factor was established. The European Portuguese version of the NOC outcome "Cognition" seems to gather very satisfactory psychometric properties for assessing cognition in the Portuguese population. This study contributed to advance the nursing body of knowledge and to better assess cognition in a clinical context.

Automedicação na comunidade: um problema de saúde pública

Introdução: A automedicação é um importante problema de saúde pública e constitui um desafio em diversos países europeus, designadamente em Portugal. Os objetivos deste estudo foram estimar a prevalência de automedicação numa amostra de adultos portugueses da Região Centro e Norte de Portugal e identificar fatores sociodemográficos e de saúde associados à automedicação. Participantes e métodos: Estudo transversal analítico. A amostra ficou constituída 197 indivíduos da comunidade, região centro e norte de Portugal, com uma média de idades de 38,26±14,20 anos e maioritariamente do género feminino (65,0%). Os dados foram recolhidos através da aplicação de um questionário, composto por questões de caracterização sociodemográfica, de contexto de saúde e questões referentes à automedicação. Resultados: No total da amostra a prevalência de automedicação ao longo da vida foi de 74,1% e nos últimos 6 meses foi de 59,9%. A automedicação ao longo da vida associou-se significativamente com a área de residência urbana (p=0,018). A automedicação nos últimos 6 meses relacionou-se positivamente com a idade ≤25 anos (OR=3,69; IC95% 1,04-12,14) e negativamente com a área de residência (rural OR=0,36; IC95% 0,15-0,84). Conclusões: Observámos elevadas prevalências de automedicação ao longo da vida e nos últimos 6 meses na comunidade norte e centro de Portugal. A automedicação associou-se com variáveis sociodemográficas e de saúde. Os resultados do presente estudo criam evidência para o planeamento de intervenções no âmbito do controlo da automedicação na comunidade.

Psychometric properties of the Negative Stereotypes Towards Aging Questionnaire (CENVE) among a sample of Portuguese adults

Stereotyped beliefs about old age and the aging process have proven to strongly promote negative behaviors toward the elderly, with unfavorable influences on their mental and physical health. Therefore, it is important to assess negative aging attitudes with brief but reliable and validated measurement instruments. The psychometric properties of the Portuguese version of the Negative Stereotypes Towards Aging Questionnaire (15 items self-reported) are explored and described in a sample of 302 participants (213 females and 89 males) between the ages of 18 and 59 years old. Confirmatory Factor Analysis shows a one-factor structure, similar to the Spanish version. The internal reliability and mean inter-item correlation showed satisfactory psychometric proprieties. Factorial ANOVA reveals that differences in agism beliefs are mainly related to educational level, with lower negative stereotypes in more educated adults. No differences were found concerning gender. This instrument may be a useful tool to assess negative stereotypes toward old age and the aging process.

The prevalence of the metabolic syndrome in Portugal: the PORMETS study

BackgroundThe PORMETS study was designed to estimate the prevalence of metabolic syndrome and its determinants in the overall and administrative regions of the Portuguese mainland.MethodsA cross-sectional study of a representative sample of non-institutionalized Portuguese adults selected from primary health care centres lists including 1695 men and 2309 women was conducted from February 2007 to July 2009. A structured questionnaire was administered, collecting information on personal medical history and socio-demographic and behavioural characteristics. Anthropometrics, blood pressure, and venous blood samples were obtained. Metabolic syndrome was defined according to three operational definitions. The prevalence ratios and their respective 95% confidence intervals were calculated using binomial generalized linear regression, with the log link function.ResultsThe prevalence rates of metabolic syndrome in this sample of Portuguese adults were 36.5%, 49.6%, and 43.1%, using the Adult Treatment Panel III, International Diabetes Federation and Joint Interim Statement definitions, respectively. The most prevalent feature of metabolic syndrome in this sample was high blood pressure (64.3%) and the lowest was high fasting glucose (24.9%). After adjustment for age and gender, significant differences were observed for the 18 districts of the Portugal mainland. Additionally, metabolic syndrome was significantly more frequent in non-urban areas than in urban ones (p = 0.001). The prevalence of metabolic syndrome was significantly higher in women (p˂0.001) and older participants (p˂0.001), as well as in those who reported being housewives (p = 0.010), retired (p = 0.046) or unemployed (p = 0.024).ConclusionsThis study showed that metabolic syndrome is highly prevalent in the Portuguese adult population. Regional differences in the prevalence of this syndrome were observed, and this condition was more common in non-urban areas and less favoured socio-economic categories.

The factor structure of the Portuguese version of the personality inventory for DSM-5 (PID-5)

IntroductionThe DSM-5 Section III proposes a dimensional-categorical model of conceptualizing personality and its disorders, which includes assessment of impairments in personality functioning (criterion A) and maladaptive personality traits (criterion B). The Personality Inventory for DSM-5 (PID-5) is a self-report, composed of 220 items, organized into 25 facets nested in five domains of personality differences, and was developed to operationalize criterion B.ObjectivesThis study explores the factor structure of the Portuguese adaptation of the PID-5.AimsThe five-factor structure that has emerged in previous studies with the PID-5 (cf. Krueger &amp; Markon) is expected to be replicated in the current study.MethodsExploratory factor analyses with varimax oblique rotation were conducted on a sample of Portuguese adults from the general population (n = 379, Mage = 31.49, SD = 14.16, 25.3% males, 74.7% females).ResultsA six factor structure was retained in which the first 5 factors resemble the PID-5 domains. The model showed good fit indices (KMO = 0.897). The total explained variance was 68.25%. All the facets but four had primary loadings on the expected factor.ConclusionsThe similarity of results across studies and nationalities contributes to the validation of the Portuguese translation of the PID-5 and highlights the structural resemblance among the DSM-5 model and the five factor model (FFM) and the personality psychopathology-five model (PSY-5), drawing attention to the relevance of these models for the diagnosis of Personality Disorders.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Quality of Life Predictors and Normative Data

This study identifies predictors and normative data for quality of life (QOL) in a sample of Portuguese adults from general population. A cross-sectional correlational study was undertaken with two hundred and fifty-five (N = 255) individuals from Portuguese general population (mean age 43 years, range 25–84 years; 148 females, 107 males). Participants completed the European Portuguese version of the World Health Organization Quality of Life short-form instrument and the European Portuguese version of the Center for Epidemiologic Studies Depression Scale. Demographic information was also collected. Portuguese adults reported their QOL as good. The physical, psychological and environmental domains predicted 44 % of the variance of QOL. The strongest predictor was the physical domain and the weakest was social relationships. Age, educational level, socioeconomic status and emotional status were significantly correlated with QOL and explained 25 % of the variance of QOL. The strongest predictor of QOL was emotional status followed by education and age. QOL was significantly different according to: marital status; living place (mainland or islands); type of cohabitants; occupation; health. The sample of adults from general Portuguese population reported high levels of QOL. The life domain that better explained QOL was the physical domain. Among other variables, emotional status best predicted QOL. Further variables influenced overall QOL. These findings inform our understanding on adults from Portuguese general population QOL and can be helpful for researchers and practitioners using this assessment tool to compare their results with normative data.
