Levine's conservation model was used as the theoretical framework for this study. A literature review was used to determine the contents of the intervention program. A nursing care program which consisted of 8 sessions, the first of which was at the hospital and the others at the homes of puerpera and which were held at different times and lasted 12 weeks in total, based on Levine's Conservation Model was provided to the women in the intervention group. Each session lasted approximately 60-120 minutes, according to the educational and practical contents.The puerpera were given trainings on different subjects based on the module during each session. For these trainings, the investigators prepared, in the light of the literature data, leaflets containing information about breastfeeding, personal hygiene, fatigue, nutrition and pilates exercises

The puerpera in the control group received only the standard nursing care given after birth. Standard nursing care contain solely breastfeeding training. The puerpera in the control group were visited before they were discharged from the hospital to obtain their contact information and to administer them the pretest. A home visit at the end of postpartum month 3 was also planned and they were administered the posttest. After collecting the posttest data, the trainings given to the women in the intervention group on nutrition, sleep, fatigue and pilates exercises were also given to the women in the control group in consideration of the ethical dimension of the study; they were actively trained on pilates exercises by the investigator and the relevant leaflets were given to them by the end of their trainings.

It is a multi-dimensional measurement tool designed by the World Health Organization to assess quality of life of individuals. The short form of the scale contains four domains and another domain where overall quality of life is evaluated. The domains are physical health, psychological health, social relationships, environment and general health. Each item in the scale is scored as a 5-point rating. Each domain assesses quality of life within itself independent of the others. Higher scores obtained in this scale indicate better quality of life. A study concluded that the short form of the scale was a valid and reliable instrument for the postpartum period. The validity and reliability study of the scale was performed in 1999 to be able to use it in Turkey and the Cronbach's α reliability coefficient of the scale was found to be 0.76 (Eser et al. 1999)

Developed by Lee et al. in 1991, the scale is used to measure the level of fatigue in healthy and ill individuals. Consisting of 18 items in total, the scale has 13 items to measure the level of fatigue and 5 items to measure the level of energy. There is a 10-cm horizontal line for each item of the scale with positive expressions on one end and negative on the other. Those who complete the scale are asked to mark the point which reflects best the feeling they had when they read the statement in the scale. Afterwards, the points of intersection at the places marked are measured with a ruler one by one for each question and evaluated objectively. Higher scores obtained from the fatigue items and lower scores obtained from the energy items indicate higher severity of fatigue. The validity and reliability study of the scale in Turkey and the Cronbach's α internal consistency coefficient of was found to be 0.90 (Yurtsever and Bedük, 2003).

Developed by Buysse and associates (1989), the index shows the sleep quality of an individual over the last month as stated by them. There are 19 questions in the index relating to sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, use of sleep medication and daytime dysfunction. Each question in the index is scored from 0 to 3. Zero shows having no trouble and 3 having serious trouble sleeping. Higher total scores indicate poorer sleep quality. The validity and reliability study of the index was performed in 1996 to be able to use it in Turkey and the Cronbach's α reliability coefficient of the index was found to be 0.80 (Ağargün et al.1996).
