Study summary

Osteoporosis is a skeletal pathology characterized by decreased bone mass and deterioration of bone tissue. This pathology affects predominantly women, which is estimated that 40% of them will suffer an osteoporotic fracture. The incidence of osteoporosis, thus representing a major public health problem where osteoporotic fractures have a higher incidence than those combined with cardiovascular disease and breast cancer (INSERM, 2016; WHO 2008). It causes traumatic fractures that have the effect of dependence and loss of functional autonomy associated, in terms, with the risk of a reduction in life expectancy. The management of osteoporosis therefore becomes an issue for rheumatologists. The latter involves both compliance with hygienic-Dietetic measures (such as calcium intake, physical activities, prevention of falls...) and medicated treatments whose action is intended, for some, to block bone destruction or, for others to stimulate bone formation. The efficacy of drug treatments is now proven, these treatments are however profitable only if the therapeutic adherence of the patients is maximal. However, rheumatologists and researchers generally find an average rate of 70% enrolment after 6 months of treatment, most often lowered to 50% after 12 months of treatment, thus increasing fractures.

On the other hand, the literature informs the medical and educational aspects of the problem of non-observance in osteoporotic patients, but curiously, it does not say anything of the psychological aspects likely to be linked to these behaviors of non-adherence to therapy.

The objective of this thesis work is to take an interest in the underlying psychological determinants that may explain the behaviour of adherence and/or non-adherence of osteoporotic patients.

What researchers measure

Primary outcomes

  1. Adherence to therapy

    The influence of psychological emission on the therapeutic adherence is measured with an adherence scale (EGOMAC) which includes 3 items: drugs observance, hygiene compliance and dietary restrictions. The item are scored on a 4-point scale with 1-strongly disagree; 2-disagree, 3-agree and 4-fully agree.

    Time frame: Day 1

Secondary outcomes

  1. Adherence to therapy

    The influence of psychological emission on the therapeutic adherence is measured with an adherence scale (EGOMAC) which includes 3 items: drugs observance, hygiene compliance and dietary restrictions. The item are scored on a 4-point scale with 1-strongly disagree; 2-disagree, 3-agree and 4-fully agree.

    Time frame: Year 1

  2. Perception of disease

    with the validated Brief Illness Perception Questionnaire.The Brief IPQ has nine items rated on a scale from 0 (minimum) to 10 (maximum). The first five assess cognitive perceptions such as effect on life; duration of illness control over illness; beliefs about the effectiveness of treatment, and experience of symptoms. Items 6 and 8 assess emotional aspects to include concern about illness and a multifaceted question about mood. Item 7 assesses degree of understanding of the illness. The final item is open-ended asking respondent to rank the 3 most impotant factors causing their illness.

    Time frame: day 1

  3. Perception of treatment

    Wit the Beliefs about Medicines Questionnaire which comprises 18 items which assesses medication beliefs in general and in specific conditions allowing for the investigation of the overall perceptions of medication in general as well as perceptions of medication in their chronic disease. The item are scored on a 5 point Likert scale with scores ranging from 4 to 20.

    Time frame: day 1

  4. Anxiety

    Anxiety is measured with the Hospital Anxiety and Depression Scale composed of 14 items, seven items for the anxiety subscale and seven for the depression subscale. Each item is scored on a response-scale with four alternatives ranging between 0 and 3. For both subscale, score of less than 7 indicates non-cases; between 8 and 10: mild; between 11 and 14: moderate and between 15 and 21: severe.

    Time frame: day 1

Ran from Jun 2019 to primary completion in Jan 2022, 31 months.

Of 22 observational studies under Osteoporosis, Postmenopausal, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 65. This study's 31 months is close to that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 9, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
