Overview

What is she best known for?

The fields of study she is best known for:

  • Cognition
  • Alzheimer's disease
  • Dementia

Janet Grace spends much of her time researching Dementia, Psychiatry, Rating scale, Physical therapy and Disease. Her Dementia research integrates issues from Alzheimer's disease, Quality of life and Gerontology. In most of her Psychiatry studies, her work intersects topics such as Clinical psychology.

Her research investigates the link between Rating scale and topics such as Frontal lobe that cross with problems in Neuropsychological test. Her Physical therapy study deals with Neuropsychology intersecting with Cohort study, Finger tapping, Physical medicine and rehabilitation, Parkinson's disease and Rehabilitation. Janet Grace studied Disease and Central nervous system disease that intersect with Multicenter study, Retrospective analysis, Deep brain stimulation and Triage.

Her most cited work include:

  • Patient versus informant perspectives of Quality of Life in Mild Cognitive Impairment and Alzheimer's disease (197 citations)
  • Assessing frontal lobe behavioral syndromes with the frontal lobe personality scale. (192 citations)
  • Factor analysis of the frontal systems behavior scale (FrSBe). (144 citations)

What are the main themes of her work throughout her whole career to date?

Janet Grace mainly investigates Psychiatry, Dementia, Clinical psychology, Disease and Audiology. Her research integrates issues of Huntington's disease and Degenerative disease in her study of Psychiatry. The concepts of her Dementia study are interwoven with issues in Alzheimer's disease, Neuropsychological test, Neuropsychology and Physical medicine and rehabilitation.

Her Alzheimer's disease research incorporates elements of Dementia with Lewy bodies, Severity of illness and Central nervous system disease. Her work on Parkinson's disease and Cognitive reserve as part of general Disease research is frequently linked to Quality of life, thereby connecting diverse disciplines of science. The various areas that she examines in her Audiology study include Developmental psychology, Verbal learning, Cognition and Stroke patient.

She most often published in these fields:

  • Psychiatry (62.07%)
  • Dementia (51.72%)
  • Clinical psychology (29.31%)

What were the highlights of her more recent work (between 2010-2016)?

  • Cognition (31.03%)
  • Psychiatry (62.07%)
  • Apathy (27.59%)

In recent papers she was focusing on the following fields of study:

Cognition, Psychiatry, Apathy, Dementia and Disease are her primary areas of study. Her work deals with themes such as Developmental psychology, Activities of daily living, Clinical psychology and Disinhibition, which intersect with Cognition. Her Objective test research extends to Psychiatry, which is thematically connected.

Her Apathy study combines topics from a wide range of disciplines, such as Frontal lobe and Psychometrics. Dementia connects with themes related to Neuropsychology in her study. She is involved in the study of Disease that focuses on Parkinson's disease in particular.

Between 2010 and 2016, her most popular works were:

  • Confirmatory Factor Analysis of the Frontal Systems Behavior Scale (FrSBe) (32 citations)
  • Confirmatory Factor Analysis of the Frontal Systems Behavior Scale (FrSBe) (32 citations)
  • Utility of the Cognitive Difficulties Scale and Association With Objective Test Performance (21 citations)

In her most recent research, the most cited papers focused on:

  • Cognition
  • Alzheimer's disease
  • Disease

Her primary areas of study are Exploratory factor analysis, Reliability, Apathy, Executive dysfunction and Frontal lobe. Among her research on Exploratory factor analysis, you can see a combination of other fields of science like Best fitting, Confirmatory factor analysis and Scale.

Related Online Degrees & Career Pathways

Exploring psychology opens doors to diverse career pathways, especially for students interested in applied behavior analysis (ABA) and Board Certified Behavior Analyst (BCBA) roles. Many universities across the USA offer online psychology degrees, which can be a stepping stone toward specialized certifications in this field.

Each state has specific requirements for becoming a BCBA. For example, if you’re interested in the Bakersfield bcba requirements, you'll find that completing approved graduate coursework and supervised experience is essential. In other regions, like Baltimore, learning about becoming a bcba in Baltimore can help you understand local licensure and examination protocols.

For students based in Idaho, meeting the bcba certification requirements in Boise involves fulfilling educational prerequisites and supervised training hours. Meanwhile, those in Massachusetts should be aware of the Boston bcba education requirements before pursuing certification.

No matter your location, an online psychology degree can provide the strong academic foundation needed for these advanced roles, supporting a rewarding career path in mental health and behavioral services.
