Objectives and Results of a Trial of the CALMA Intervention
CALMA was a home-based intervention in which trained counselors delivered eight educational modules about asthma that were culturally tailored for a low-income Puerto Rican population. A randomized, controlled trial was performed to assess the effectiveness of the CALMA intervention in reducing asthma morbidity in poor Puerto Rican children with persistent asthma, and in increasing caregivers’ confidence in managing their child’s asthma. The randomized, controlled trial was approved by the University of Puerto Rico’s Institutional Review Board. As reported,27
children in the CALMA intervention group did better than children in the control group in terms of having 6.5% more symptom-free nights, three times greater control of their asthma, 37% fewer visits to the emergency room, and 68% fewer hospitalizations. Also, caregivers in the intervention group felt more confident in their ability to manage their child’s asthma.
CALMA was developed according to the eight CBPR principles outlined by Israel et al.28
Additionally, the CALMA intervention was designed to educate families on how to manage modifiable individual, family, and environmental factors through behavior modification. The intervention was guided by the 2002 NAEPP’s Guidelines for the Diagnosis and Management of Asthma,29
which were the most recent guidelines at the time of CALMA’s development. Finally, CALMA was developed in a culturally sensitive manner. Implementation of the eight CBPR principles28
in CALMA’s development is described below.
Principle 1: Recognize Community as a Unit of Identity
The CALMA project began in the summer of 2003 when the collaborators formally recognized themselves as an asthma community. The community was broadly defined as diverse members from the local, professional, and medical community, academia, and local government with a vested interest in the health outcomes of Puerto Rican children with asthma. The CALMA intervention was originally conceived by the academic partners, who already maintained collaborative relationships with some pediatric pulmonologists in the community. Early discussions between the academic partners and local medical professionals elucidated the reality that successful implementation of the CALMA intervention for low-income families would not be possible without the collaboration of a diverse group of stakeholders. Together, the academic and medical partners brainstormed which types of organizations and individuals would be beneficial and sought out these potential partners. As new partners committed to the project, they provided additional insight regarding potential collaborators in a cyclical fashion.
Establishing the CALMA community was a long and often arduous process. Commitment to the CALMA project from some collaborators, such as the medical professionals and the Puerto Rico Public Health Department and Health Insurance Administration, was necessary before submitting the grant for the project. Other key partnerships, such as those with caregivers and the Asthma Coalition of Puerto Rico, were sought after grant submission. The formation of the CALMA community was unique in that the researchers were not “outsiders” looking to improve health conditions for a minority group, but were all island Puerto Ricans with preestablished connections to the target community.
The target intervention community was defined as children living in Puerto Rico between the ages of 5 and 12 enrolled in the Puerto Rican government health insurance plan and diagnosed with moderate to severe asthma as defined by the Health Plan Employer Data Information Set and the Puerto Rican Department of Health. In order to qualify for the government health insurance plan at the time of CALMA’s implementation, families must have earned 200% of the federal poverty level or less. Children from low socioeconomic families were targeted for this intervention owing to the link between poverty and asthma prevalence and severity.30,31
Principle 2: Build on Strengths and Resources Within the Community
The CALMA community drew on its personal knowledge and experience to develop a culturally sensitive intervention. Rather than implementing an extant asthma intervention in its entirety, the CALMA community adopted elements of interventions (the A+ Asthma program,32
modified by The Johns Hopkins University’s National Cooperative Inner-City Asthma Study and Proyecto AIRE
developed at the University of Puerto Rico), modifying and creating unique components that were culturally tailored for Puerto Rican families. Of the eight educational modules in CALMA (), four of the modules were created specifically to address the needs of Puerto Rican families (see Principal 4) and the remaining four were modified to include culturally relevant information. For example, in the educational module addressing the causes and symptoms of asthma—What is Asthma?—CALMA partners addressed common myths held by island Puerto Ricans.34
Such myths included beliefs that asthma is caused by an untreated cold or flu, strong positive or negative emotions, and getting wet while sweating (as can occur when children are playing in hot and humid weather and it begins to rain).
Asthma Modules Included in CALMA
In the Asthma Triggers module, CALMA collaborators included climate-specific triggers, such as cockroaches, humidity, and mold, which may not be as prominent in less temperate climates, as well as geographic-specific triggers, such as Sahara dust. The Asthma Treatment and Asthma Treatment Plan modules were culturally tailored by including only the medications covered by the government health insurance plan. Home remedies believed to be effective asthma treatments for children, such as herbal teas, shark oil, and putting hot water on the chest,34
were also incorporated into the intervention training materials. Asthma counselors emphasized the importance of discussing any use of home remedies with the primary care physician, because some remedies could be dangerous. For example, camphor is frequently used as a cough suppressant or to relieve congestion, but can be toxic to children if applied too liberally or if ingested. Finally, the adopted intervention modules also underwent a rigorous translation and adaptation process to ensure content clarity and cultural sensitivity for Puerto Ricans.35
Culturally congruent pictures of families with similar appearance to the participants were also incorporated into the educational materials.
Principle 3: Facilitate Collaborative Partnerships in All Phases of the Research
Collaborative partnerships were promoted through the creation of a multidisciplinary panel and focus groups for parents with asthmatic children. The multidisciplinary panel consisted of pediatric pulmonologists, psychologists, nurses, program evaluators, health educators, environmental scientists, academic researchers, and parents of children with asthma. The panel held monthly meetings to develop and discuss each version of the intervention, specifically focusing on its applicability to low-income Puerto Rican families. Specific topics included reviewing the medical content and the environmental triggers for accuracy and relevance to the community, examining the emotional effects and stress experienced by families affected by asthma, standardizing the delivery of the intervention, and developing an intensive asthma counselor certification training program.
Principle 4: Integrate Knowledge and Action for Mutual Benefit of All Partners
CALMA collaborators from local, professional, and medical communities; academia; and government agencies contributed their unique perspectives in the development of the intervention (). At the local level, focus groups conducted with caregivers of children with asthma resulted in the development of the four educational modules unique to CALMA (). The module entitled “Asthma and the Family” addressed the caregivers’ concerns regarding asthma’s stressful effects on the family and marital relationships. These stressors included long waits in the emergency room, lost income owing to caring for an asthmatic child who is too ill to go to school, and poor or inadequate care resulting from a lack of financial resources. Because low-income Puerto Rican families may face multiple barriers to receiving high-quality asthma care, methods on how to empower caregivers to overcome barriers were addressed in the “Empowerment: Overcoming Barriers in Asthma Management” module. For example, many caregivers expressed difficulty in asking appropriate questions of their child’s pediatrician regarding asthma management. As a result, suggestions on how to better communicate with health care providers were included. The “Educating your Child and Others about Asthma” module delineated how to educate children, family members, and other caretakers about appropriate asthma management. Because of the prevalence of extended family providing assistance with child care, the module provided details on how to react appropriately to the sudden onset of a child’s asthma symptoms. A final module, summarizing all of the previous modules, called “Final Recommendations,” was suggested by caregivers as a means to facilitate easy understanding of CALMA by families with lower levels of education and literacy. In addition, caregivers stressed the importance of making CALMA interactive, engaging the families during the intervention and assigning homework to maintain focus between sessions.
Contributions Made and Benefits Received by CALMA Partners
The professional and medical asthma partners contributed area-specific knowledge to provide a comprehensive understanding of the scientific aspects of asthma. For example, community physicians and a local pharmaceutical company reviewed the intervention’s medical content for accuracy and descriptions on medication use for effectiveness. In collaboration with caregivers, local physicians developed a table of asthma medications available to low-income families, their benefits, side effects, and whether they should be used as rescue or control medications to simplify the information presented on asthma treatment. Two local private health insurance companies also provided helpful information regarding insurance claims and the specific asthma medications covered by their plans.
Academic partners contributed significantly to the conceptualization, design, and implementation of the study. Researchers relayed previous research findings regarding pediatric asthma,7–9
asthma in Puerto Rico,1–4
asthma management interventions,11–14
and the role of CBPR and cultural sensitivity in effective asthma management.15,26
This information was used by the CALMA community to make project decisions. Researchers coordinated the caregiver focus groups, the multidisciplinary panel meetings, and training sessions to standardize the asthma counselors in the intervention.
The Puerto Rico Health Department and Health Insurance Administration both provided important data on the targeted community, such as service use rates, and access to the target community. Forming an alliance with the Health Insurance Administration can be beneficial because they can assist with the implementation of effective interventions into the health care system. The Puerto Rico Ombudsman Department provided information on patient’s rights as well as common complaints made by asthma patients, such as the cost of medication and pharmacy wait times.36
In addition to the specific group contributions, the CALMA community worked for 3 years to develop the intervention and reviewed 11 drafts for content clarity and comprehension before all partners approved it.
Principle 5: Promote a Co-Learning and Empowering Process That Attends to Social Inequalities
Co-learning was a natural and expected result of the collaboration. In addition, the CALMA community recognized its utility and incorporated co-learning into CALMA’s implementation. Thus, asthma counselors learned the specific needs and obstacles each family faced, and worked to empower families to modify individual and environmental factors in an effort to decrease asthma morbidity in their children. The CALMA intervention sought to empower low-income families to (1) understand the nature (chronicity) of asthma; (2) identify barriers to care and to appropriate medication usage; (3) better understand the different types of medications and how to use them; (4) appropriately use the health care system and keep follow-up appointments; (5) enhance use of action plans; (6) improve identification of asthma triggers and environmental avoidance techniques; (7) encourage identification of symptom onset and early management; (8) assume an active role in the communication with the provider; and (9) identify asthma-related stressors that may affect the psychological well-being of the parent and identify helpful resources or therapeutic options.
Principle 6: Involve a Cyclical and Iterative Process
Substantive efforts were taken to identify community partners who were committed to decreasing asthma morbidity in Puerto Rican children. Because sustainable interventions are never final, action, reflection, and modification phases should be continuously repeated.37
In terms of CALMA, the action phase included the development and implementation of the intervention in the target community. The reflection phase included the evaluation of the intervention. Study results demonstrated that in comparison to families in a control group, CALMA parents’ asthma knowledge and confidence increased while their child’s night-time asthma symptoms decreased and service utilization improved (see Canino et al27
for details). However, day-time asthma symptoms did not differ between children receiving the CALMA intervention or a control treatment. After considering these results, the CALMA community decided that the intervention was successful, but that continued collaboration would be necessary to improve the intervention. Subsequently, CALMA collaborators have begun expanding the intervention to not only address family asthma management, but to improve the quality of care that physicians in government-sponsored health clinics provide their asthma patients. In addition, other organizations have adopted the CALMA intervention (see Principle 8) and must use their own iterative process to continually transform the intervention in a way that sufficiently meets the needs of their specific target communities.
Principle 7: Address Health From Both Positive and Ecological Perspectives
Traditional asthma management interventions tend to focus primarily on biomedical and environmental factors that relate to asthma while ignoring other pertinent factors. However, the CALMA community specifically identified additional factors that impact asthma management in Puerto Rico. CALMA incorporates modules that address the psychological and financial stresses that having a child with asthma places on the family. Examples of these restrictions include absence from social activities and limitations to the types of medications that are provided under government-sponsored health care. Managing asthma using ecological and positive health approaches may address health-related concerns better than examining asthma primarily through a medical lens because it incorporates multiple perspectives and makes the information more accessible for families who experience the consequences of asthma in a variety of domains.
Principle 8: Disseminate Findings and Knowledge Gained to All Partners
Results from the CALMA intervention have been disseminated in both academic and public outlets. Within Puerto Rico, the Department of Education has used the CALMA materials in an island-wide initiative to educate school nurses about asthma and the correct use of asthma medication. A local pharmaceutical company has already sponsored the training of 40 school nurses in the application of CALMA. In addition, a second pharmaceutical company is planning to adopt CALMA for an upcoming asthma education campaign, and the School of Pharmacy at the University of Puerto Rico has implemented CALMA as part of its training. Thus, given continued interest and adaptation of CALMA in a variety of forums, program sustainability seems promising.
