    Development and validation of a nutrition knowledge questionnaire for a Canadian population
    (Published on behalf of the Nutrition Society by CAB International, 2016-12-27) Carbonneau, Élise; Corneau, Louise; Bradette-Laplante, Maude; Lemieux, Simone; Vohl, Marie-Claude; Robitaille, Julie; Desroches, Sophie; Bégin, Catherine; Provencher, Véronique
    Objective: The present study aimed to develop and validate a nutrition knowledge questionnaire in a sample of French Canadians from the province of Quebec, taking into account dietary guidelines. Design: A thirty-eight-item questionnaire was developed by the research team and evaluated for content validity by an expert panel, and then administered to respondents. Face validity and construct validity were measured in a pre-test. Exploratory factor analysis and covariance structure analysis were performed to verify the structure of the questionnaire and identify problematic items. Internal consistency and test-retest reliability were evaluated through a validation study. Setting: Online survey. Subjects: Six nutrition and psychology experts, fifteen registered dietitians (RD) and 180 lay people participated. Results: Content validity evaluation resulted in the removal of two items and reformulation of one item. Following face validity, one item was reformulated. Construct validity was found to be adequate, with higher scores for RD v. non-RD (21·5 (sd 2·1) v. 15·7 (sd 3·0) out of 24, P<0·001). Exploratory factor analysis revealed that the questionnaire contained only one factor. Covariance structure analysis led to removal of sixteen items. Internal consistency for the overall questionnaire was adequate (Cronbach's α=0·73). Assessment of test-retest reliability resulted in significant associations for the total knowledge score (r=0·59, P<0·001). Conclusions: This nutrition knowledge questionnaire was found to be a suitable instrument which can be used to measure levels of nutrition knowledge in a Canadian population. It could also serve as a model for the development of similar instruments in other populations.

    Development and validation of the food liking questionnaire in a french-canadian population
    (MDPI Pub., 2017-12-08) Carbonneau, Élise; Bradette-Laplante, Maude; Lamarche, Benoît; Vohl, Marie-Claude; Robitaille, Julie; Desroches, Sophie; Bégin, Catherine; Provencher, Véronique
    The purpose of this study was to develop and validate a questionnaire assessing food liking in a French-Canadian population. A questionnaire was developed, in which participants were asked to rate their degree of liking of 50 food items. An expert panel evaluated the content validity. For the validation study, 150 men and women completed the questionnaire twice. An Exploratory Factor Analysis (EFA) was performed to assess the number of subscales of the questionnaire. Internal consistency and test-retest reliability of the subscales were evaluated. Concurrent validity was assessed through correlations between liking scores and self-reported frequencies of consumption. Comments from the experts led to changes in the list of foods included in the questionnaire. The EFA revealed a two-factor structure for the questionnaire (i.e., savory and sweet foods) and led to the removal of nine items, resulting in a 32-item questionnaire. The two subscales revealed good internal consistency (Cronbach alphas: 0.85 and 0.89) and test-retest reliability (p = 0.84 and 0.86). The questionnaire demonstrated adequate concurrent validity, with moderate correlations between food liking and self-reported frequency of consumption (r = 0.19–0.39, ps < 0.05). This new Food Liking Questionnaire assessing liking of a variety of savory and sweet foods demonstrated good psychometric properties in every validation step. This questionnaire will be useful to explore the role of food liking and its interactions with other factors in predicting eating behaviors and energy intake.

    Factors influencing the adoption of a healthy eating campaign by federal cross-sector partners : a qualitative study
    (BioMed Central, 2016-08-30) Dufour, Joëlle; Turcotte, Mylène; Fernandez, Melissa Anne; Marquis, Marie; Desroches, Sophie; Provencher, Véronique
    Background: The Eat Well Campaign (EWC) was a social marketing campaign developed by Health Canada and disseminated to the public with the help of cross-sector partners. The purpose of this study was to describe factors that influenced cross-sector partners’ decision to adopt the EWC. Methods: Thematic content analysis, based primarily on an a priori codebook of constructs from Roger’s diffusion of innovations decision process model, was conducted on hour-long semi-structured telephone interviews with Health Canada’s cross-sector partners (n = 18). Results: Dominant themes influencing cross-sector partners’ decision to adopt the EWC were: high compatibility with the organization’s values; being associated with Health Canada; and low perceived complexity of activities. Several adopters indicated that social norms (e.g., knowing that other organizations in their network were involved in the collaboration) played a strong role in their decision to participate, particularly for food retailers and small organizations. The opportunity itself to work in partnership with Health Canada and other organizations was seen as a prominent relative advantage by many organizations. Adopters were characterized as having high social participation and positive attitudes towards health, new ideas and Health Canada. The lack of exposure to the mass media channels used to diffuse the campaign and reserved attitudes towards Health Canada were prominent obstacles identified by a minority of health organizations, which challenged the decision to adopt the EWC. Most other barriers were considered as minor challenges and did not appear to impede the adoption process. Conclusions: Understanding factors that influence cross-sector adoption of nutrition initiatives can help decision makers target the most appropriate partners to advance public health objectives. Government health agencies are likely to find strong partners in organizations that share the same values as the initiative, have positive attitudes towards health, are extremely implicated in social causes and value the notion of partnership

    Salient beliefs among Canadian adults regarding milk and cheese consumption : a qualitative study based on the theory of planned behaviour
    (BioMed Central, 2016-08-09) Painchaud Guérard, Geneviève; Lacroix, Marie-Josée; Turcotte, Mylène; Couture, François.; Desroches, Sophie; Paquin, Paul; Provencher, Véronique
    Background In spite of multiple efforts by public health authorities to promote consumption of milk and alternatives in the Canadian adult population, consumption of these healthy foods is still suboptimal. This study aimed to explore salient beliefs underlying the consumption of fluid milk and cheese among adults. Methods The qualitative descriptive research design was based on the Theory of Planned Behaviour framework, using 20 focus groups. A total of 161 men and women (19 to 50 years old) from Quebec City, Montreal and Toronto (Canada) were recruited to participate in focus groups. A hybrid approach (deductive and inductive) to qualitative methods of thematic analysis was used during coding of focus group transcripts to draw out participant’s salient beliefs regarding milk and cheese consumption. Results For both milk and cheese, most groups cited advantages or disadvantages with regards to health effects, nutritional value, taste, socio-affective aspects and practicality. Family and friends, health professionals and advisors, and communications domain (e.g. advertisements, TV programs, well-known personalities) were cited as major influences affecting consumption. Price reduction, product improvements, supply increase and variation, favourable food/drink combinations and access were among the most commonly cited facilitators for milk and cheese consumption. Major barriers included high price, reduced confidence in the product (reasons/contexts that reduce perceived safety of the product), health status, problems linked to supply (varieties/formats which are not available), and habits and cultural values. Gender and level of milk and cheese consumption differences were observed between groups: men referred more often to industry and politics as factors influencing their milk consumption, while women expressed more animal and environmental concerns. Differences were also noted between high and low consumer’s groups in relation to the themes of taste, pleasure and emotions for milk and cheese consumption. Lastly, low consumers expressed more distrust and disgust relating to milk consumption than high consumers. Conclusions The majority of beliefs observed are consistent with earlier studies on milk or dairy product consumption. Consumers’ concerns about origins of milk, however, have never been reported. These findings will help optimize approaches for promoting consumption of these foods among different segments of Canadian adults.

    A comparative content analysis of vegetarian food blogs written by registered dietitians and non- registered dietitians
    (Dietitians of Canada = Diététistes du Canada., 2017-03-23) Dugrenier, Marilyn; Lapointe, Annie.; Lemieux, Simone; Dumas, Audrée-Anne; Desroches, Sophie
    This purpose of this study was to compare the nutritional content of vegetarian recipes published in food blogs written by registered dietitians (RDs) and by non-registered dietitians (non-RDs). Twelve food blogs written by RDs and 12 written by non-RDs were selected using a systematic approach. For each food blog, 2 vegetarian entrée recipes per season were selected (n = 192 recipes). Descriptive analyses were performed using Fisher’s exact test. Median nutritional values per serving between RDs’ and non-RDs’ recipes were compared using Wilcoxon–Mann–Whitney tests. RDs’ recipes were significantly lower in energy, non-heme iron, vitamin C, and sodium, contained significantly more vitamin D and had a higher protein proportion than non-RDs’ recipes. Disparities were also observed across type of entrée and vegetarian dietary pattern. In conclusion, this study showed that RD and non-RD food bloggers provided vegetarian recipes with few nutritional differences. Whether expanding the comparative analysis between RDs and non-RDs’ blogs targeting different nutrition-related topics would yield different results remains to be investigated.

    Assessing patients' involvement in decision making during the nutritional consultation with a dietitian
    (John Wiley & Sons Ltd, 2014-07-17) Lapointe, Annie.; Vaillancourt, Hugues; Desroches, Sophie; Deschênes, Sarah-Maude; Légaré, France
    Background Shared decision making (SDM) represents an interesting approach to optimize the impact of dietary treatment, but there is no evidence that SDM is commonly integrated into diet-related health care. Objective To assess the extent to which dietitians involve patients in decisions about dietary treatment. Methods We audiotaped dietitians conducting nutritional consultations with their patients, and we transcribed the tapes verbatim. Three trained raters independently evaluated the content of the nutritional consultations using a coding frame based on the 12 items of the French-language version of the OPTION scale, a validated and reliable third-observer instrument designed to assess patients’ involvement by examining specific health professionals’ behaviours. Coding was facilitated by the qualitative research software NVivo 8. We assessed internal consistency with Cronbach’s alpha and inter-rater reliability with the intraclass correlation coefficient (ICC). Results Of the 40 dietitians eligible to participate in the study, 19 took part. We recruited one patient per participating dietitian. The overall mean OPTION score was 29 ± 8% [range, 0% (no patient involvement in the decision] to 100% [high patient involvement)]. The mean duration of consultations was 50 ± 26 min. The OPTION score was positively correlated with the duration of the consultation (r = 0.65, P < 0.01). Internal consistency and inter-rater reliability were both good (Cronbach’s alpha = 0.72; ICC = 0.65). Conclusion This study is the first to use a framework based on the OPTION scale to report on dietitians’ involvement of patients in decisions about patients’ dietary treatment. The results suggest that involvement is suboptimal. Interventions to increase patients’ involvement in diet-related decision making are indicated.

    Postmenopausal women with abdominal obesity choosing a nutritional approach for weight loss: A decisional needs assessment
    (Elsevier, 2016-08-19) Lapointe, Annie.; Poirier, Nadine; Stacey, Dawn; Lemieux, Simone; Desroches, Sophie; Bégin, Catherine; Légaré, France
    Objectives: To identify the decisional needs of postmenopausal women with abdominal obesity choosing between two nutritional approaches for weight loss: a low-fat diet or a diet rich in fruit and vegetables. Study design: Our descriptive qualitative study was based on the Ottawa Decision Support Framework. Main outcome measures: Four focus groups were conducted with postmenopausal women. A thematic content analysis was performed to determine the decisional needs influencing the choice of a low-fat diet or a diet rich in fruit and vegetables. Results: Seventeen postmenopausal women participated in the study (median age 59 years). Most frequently reported decisional needs for each nutritional approach were sufficient levels of nutritional skills and knowledge, consideration of the physiological impacts and the sensory aspect of approaches, food availability, social support, finances and motivation. Partners, friends and daughters were considered as the most important individuals involved in the decision. Conclusions: We identified several decisional needs influencing postmenopausal women when choosing between a low-fat diet and a diet rich in fruit and vegetables. These findings could inform the design of decision support interventions that address the decisional needs of women for making and implementing informed decisions about a nutritional approach for weight loss.

    Psychosocial factors of dietitians’ intentions to adopt shared decision making behaviours : a cross-sectional survey
    (Public Library of Science, 2013-05-20) Deschênes, Sarah Maude; Lapointe, Annie.; Turcotte, Stéphane; Gagnon, Marie-Pierre; Desroches, Sophie; Légaré, France
    Objectives While shared decision making (SDM) promotes health-related decisions that are informed, value-based and adhered to, few studies report on theory-based approaches to SDM adoption by healthcare professionals. We aimed to identify the factors influencing dietitians' intentions to adopt two SDM behaviours: 1) present dietary treatment options to patients and 2) help patients clarify their values and preferences. Methods We conducted a cross-sectional postal survey based on the Theory of Planned Behaviour among 428 randomly selected dietitians working in clinical practice across the Province of Quebec, Canada. We performed descriptive analyses and multiple regression analyses to determine the variables that explained the variance in intention to perform the behaviours. Results A total of 203 dietitians completed the questionnaire. Their ages were from 23 to 66 and they had been practising dietetics for 15.4±11.1 years (mean ± SD). On a scale from 1 to 7 (from strongly disagree to strongly agree), dietitians' intentions to present dietary treatment options and to clarify their patients' values and preferences were 5.00±1.14 and 5.68±0.74, respectively. Perceived behavioural control (ß¿=¿0.56, ¿<0.0001), subjective norm (ß¿=¿0.16, ¿<0.05), and moral norm (ß¿=¿0.22, ¿<0.0001), were the factors significantly predicting the intention to present dietary treatment options, while perceived behavioural control (ß¿=¿0.60, ¿<0.0001), attitude (ß¿=¿0.20, ¿<0.05), and professional norm (ß¿=¿0.22, ¿<0.001), significantly predicted the intention to help patients' clarify their values and preferences.

    Exploration of shared decision‐making processes among dieticians and patients during a consultation for the nutritional treatment of dyslipidaemia
    (Blackwell Science, 2014-08-18) Lapointe, Annie.; Vaillancourt, Hugues; Gagnon, Marie-Pierre; Desroches, Sophie; Deschênes, Sarah-Maude; Légaré, France
    Background: Shared decision making (SDM) holds great potential for improving the therapeutic efficiency and quality of nutritional treatment of dyslipidaemia by promoting patient involvement in decision making. Adoption of specific behaviours fostering SDM during consultations has yet to be studied in routine dietetic practice. Objective: Using a cross-sectional study design, we aimed to explore both dieticians’ and patients’ adoption of SDM behaviours in dietetic consultations regarding the nutritional treatment of dyslipidaemia. Methods: Twenty-six dieticians working in local health clinics in the Quebec City metropolitan area were each asked to identify one dyslipidaemic patient they would see in an upcoming consultation. Based on the Theory of Planned Behaviour (TPB), questionnaires were designed to study two targeted SDM behaviours: ‘to discuss nutritional treatment options for dyslipidaemia’ and ‘to discuss patients’ values and preferences about nutritional treatment options for dyslipidaemia’. These questionnaires were administered to the dietician–patient dyad individually before the consultation. Associations between TPB constructs (attitude, subjective norm and perceived behavioural control) towards behavioural intentions were analysed using Spearman’s partial correlations. Results: Thirteen unique patient-dietician dyads completed the study. Perceived behavioural control was the only TPB construct significantly associated with both dieticians’ and patients’ intentions to adopt the targeted SDM behaviours (P < 0.05). Conclusions: As perceived behavioural control seems to determine dieticians’ and patients’ adoption of SDM behaviours, interventions addressing barriers and reinforcing enablers of these behaviours are indicated. This exploratory study highlights issues that could be addressed in future research endeavours to expand the knowledge base relating to SDM adoption in dietetic practice.

    Social support, but not perceived food environment, is associated with diet quality in French-speaking Canadians from the PREDISE study
    (M D P I AG, 2019-12-12) Carbonneau, Élise; Bélanger, Mathieu; Couillard, Charles; Corneau, Louise; Lamarche, Benoît; Lemieux, Simone; Vohl, Marie-Claude; Bouchard, Luigi; Robitaille, Julie; Pelletier, Luc G.; Desroches, Sophie; Houle, Julie; Bégin, Catherine; Langlois, Marie-France; Provencher, Véronique
    The objectives were to assess whether social support for healthy eating and perceived food environment are associated with diet quality, and to investigate if sociodemographic characteristics moderate these associations. A probability sample of French-speaking adults from the Province of Québec, Canada, was recruited in the context of the PREDISE study. Participants reported their perceptions of supportive and non-supportive actions related to healthy eating from close others at home and outside of home (n = 952), and of the accessibility to healthy foods (n = 1035). The Canadian Healthy Eating Index (C-HEI) was calculated based on three Web-based 24 h food recalls. Multiple linear regression models showed that supportive (B = 1.50 (95% CI 0.46, 2.54)) and non-supportive (B = −3.06 (95% CI −4.94, −1.18)) actions related to healthy eating from close others at home were positively and negatively associated with C-HEI, respectively, whereas actions from close others outside of home were not. The negative association between non-supportive actions occurring at home and C-HEI was stronger among participants with lower (vs. higher) levels of education (p interaction = 0.03). Perceived accessibility to healthy foods was not associated with C-HEI (p > 0.05). These results suggest that the social environment may have a stronger influence on healthy eating than the perceived physical environment. This adds support for healthy eating promotion programs involving entire families, especially for more socioeconomically disadvantaged individuals, whose efforts to eat healthily may be more easily thwarted by non-supportive households
