Study Details

Study Description

Brief Summary

This study is a randomized single-blind controlled trial with parallel arms.The present study is based on that previously published by Pezzati and collegues (2014) and it is part of a larger project focusing on Doll Therapy dissemination in Canton Ticino through team training and supervision and guidelines definition that led to the establishment of the Ticino Doll Therapy Group with support of the Canton Office for elderly and home care.

The first hypothesis regards the 30 days-effectiveness efficacy of the Doll Therapy intervention in reducing symptoms of behavioral disorders (BPSD) that appear in stressful situations (as in the case of a separation from a professional caregiver) and in reducing stress as perceived by the treating physician. Another issue to be investigated is whether the typical way in which a person manifested attachment behaviors during own life (classified in three types of mental states: secure, insecure and unresolved) is associated, once this person is in an advanced stage of dementia, with caregiving behaviors of the PWD during the doll presentation (i.e. caressing the object, talking to it and smiling).

Detailed Description

Primary goals The primary goal of the present study is to evaluate the efficacy of Doll Therapy Intervention (DTI) versus a Sham Intervention (SI), on behavioral and psychiatric symptoms of PWD living in a nursing home. Outomes will be measured with the Italian version of Neuropsychiatric Inventory-Nursing Home. It is expected an improvement in terms of a decrease in NPI-NH total score.

We will also assess the efficacy of DTI versus SI, on professional caregivers distress ratings related to behavioral and psychiatric symptoms of PWD. It will be measured with the Italian version of NPI-NH. It is expected an improvement in terms of a decrease in NPI-NH distress total score.

It will also assess the efficacy of DTI versus SI, on cognitive and physiological status of PWD. The first will be recorded as the presence or absence of exploratory and caregiving behaviors on an observational grid expressly conceived for this purpose (Grid 2, Appendix). It is expected an improvement in terms of an increase of the number and duration of exploratory and caregiving behaviors. The efficacy of DTI versus SI on physiological status of PWD will be measured by assessing blood pressure (systolic and diastolic), heart rate, and salivary cortisol that are biomarkers of acute stress. It is expected an improvement in terms of a decrease in these parameters.

All evaluations will be performed at baseline (T0) and thirty days later (T1). Secondary goal The secondary goal is to evaluate the stability of attachment behaviors of the PWD through the adminstration of the Adult Attachment Interview to the patients' offspring after conclusion of interventions. It is expected to find an association between the attachment style of the PWD and caregiving behaviors during the doll presentation (i.e. caressing the object, talking to it and smiling). Such behaviors are recorded in an observational grid expressely conceived for this purpose.

These observations will allow the investigators to test wether a relationship between present and past attachment style of PWD and between attachment styles and participant response to doll therapy exist. Investigators expect that PWD with a previous secure attachment style will accept the doll and will show caregiving behaviors, while the PWD with insecure attachment style will show, especially during the first contacts, rejection, avoidance of the doll or excessive caregiving reactions towords the doll. Investigators also expect that PWD with unresolved attachment style will show inconsistent responses to the presentation of the doll, with approaching and rejecting behaviors.

Study Design

Study Type:

Interventional

Anticipated Enrollment :

128 participants

Allocation:

Randomized

Intervention Model:

Parallel Assignment

Intervention Model Description:

Each participant will undergo daily sessions of DTI or SI, lasting an hour at most, led by a trained professional caregiver. The DTI involves the presentation of a doll produced by a Swedish brand conceived for Doll Therapy use. The SI group will attend similar daily sessions, but in place of the doll, it will be presented with a non-anthropomorphic object, i.e., a soft foam rubber cube covered with a coloured and velvety textile. The 1st and 30th session of all participants will be videotaped by a trained psychologist as described below. The experimental protocol is described in detail in Pezzati et al. (2014) and it is structured with the goal of recreating a situation of (1) separation from a known figure and (2) interaction with the environment in order to partially recreate the prototypical phases of the "Strange situation" (Ainsworth et al., 1978).Each participant will undergo daily sessions of DTI or SI, lasting an hour at most, led by a trained professional caregiver.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Doll Therapy Intervention (DTI) The DTI involves the presentation of a doll produced by a Swedish brand and conceived for Doll Therapy use. It is designed to recreate the sensation of touching, looking and holding a child in the arms. The doll presentation involves five standard steps: A nurse (whom the patient knows) accompanies the patient in the room and invites her to sit on the chair. The nurse presents the object (doll or cube) to the patient. The nurse leaves the patient alone with the object. Interaction with the object: it lasts 3 minutes starting from the moment when the nurse leaves the room. This phase is interrupted if the patient drops the object before the time limit. The nurse returns into the room and takes back the object.	Behavioral: Doll Therapy Intervention Daily sessions, lasting an hour, will take place in a room known to patients (P). The only people in the room will be a nurse (N) and the researcher with video-tape, never interacting with P. The procedure is: the N will accompany the P in the room and the P will take a seat. The N will put the doll in front of the P and will say "Good morning Mr./Mrs....look", with a quiet voice. If the P will not take it at the first attempt, the N will sit down in front of her holding the doll in the arms and will wait for 2 minutes. The N will invite the PWD again. If the P will not take the doll after the second request, the N will not insist and she will leave. If the doll will be taken, the N will leave the P and say "I have to go, goodbye Mr./Mrs. . . ..". The gaze will always be upon the P.
Active Comparator: Active control group (SI) The SI involves the presentation of a non-anthropomorphic object, a soft foam rubber cube covered with a coloured and velvety textile. The procedure is the following: A nurse (whom the patient knows) accompanies the patient in the room and invites her to sit on the chair. The nurse presents the cube to the patient. The nurse leaves the patient alone with the cube. Interaction with the cube: it lasts 3 minutes starting from the moment when the nurse leaves the room. This phase is interrupted if the patient drops the object before the time limit. The nurse returns into the room and takes back the cube.

Outcome Measures

Primary Outcome Measures

Behavioral and psychiatric symptoms [from baseline (T0) to 30 days since the beginning of intervention (T1)]
A decrease of the behavioral and psychiatric symptoms of patient measured as the net change in the total scores of the Nursing Home version of NPI (NPI-NH total score) from baseline to post-intervention. It is expected a significant difference in NPI-NH total scores between experimental and active control group. The NPI-NH will be administered to the team of the nursing home by a trained blinded psychologist. The NPI-NH is specifically designed for interviewing professional care facility staff.
Professional caregiver distress [from baseline (T0) to 30 days since the beginning of intervention (T1).]
A decrease of the professional caregiver distress ratings related to behavioral and psychiatric symptoms of patient. It is measured as the net change in the distress total score of the Nursing Home version of NPI (NPI-NH-D total score) from baseline to post-intervention.
Interaction with the object [from baseline (T0) to 30 days since the beginning of intervention (T1)]
An increase of the duration (expressed in seconds) of the interaction with the object: it is expected a significant difference in duration between experimental and control group. This measure is recorded by professional caregivers during the daily sessions of DTI or SI.
Salivary cortisol [from the time immediately before to 15 minutes after each daily sessions of DTI or SI]
Salivary cortisol is a biomarker of stress, and its secretion is the final product of the activation of stress-response mechanisms, specifically the hypothalamic-pituitary-adrenal axis. It is expected a significantly different decrease of the concentration of salivary cortisol between experimental and control group.
Blood pressure [ffrom the time immediately before to 15 minutes after each daily sessions of DTI or SI]
A significantly different decrease of the blood pressure (systolic and diastolic) of the patients between experimental and control group.
Heart rate [from baseline (T0) to 30 days since the beginning of intervention (T1).]
A significantly different decrease of the heart rate of the patients between experimental and control group.

Secondary Outcome Measures

association between the pre-morbid attachment style of PWD and the response to DTI [after 30 days since the beginning of intervention (T1)]
The Adult Attachment Interview (AAI) is a semi-structured interview administered to children of the patients in the DTI group in order to identify mental states related to attachment style. Since a correspondence of 75% between the individual's attachment and that of the own children has been reported, the AAI is a useful instrument to recognize the pre-morbid attachment style of patient. It is video-recorded, and the labeling of the answers is carried out by an external trained and authorized psychologist. it is expected a significant association between the pre-morbid attachment style of patient and the response to DTI.
