Objective [Heading]	rr_ObjectiveHeading	Investment Objectives
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Fund’s investment objective is to provide a high level of current income by investing in a diversified portfolio consisting principally of fixed-income securities, which may include both non-convertible and convertible debt securities and preferred stocks.
Objective, Secondary [Text Block]	rr_ObjectiveSecondaryTextBlock	As a secondary objective the Fund will seek capital appreciation, but only when consistent with its primary objective.
Expense [Heading]	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that are incurred, directly or indirectly, when a variable product owner buys, holds, or redeems interest in an insurance company separate account that invests in the Series I shares of the Fund but does not represent the effect of any fees or other expenses assessed in connection with your variable product, and if it did, expenses would be higher.
Shareholder Fees Caption [Text]	rr_ShareholderFeesCaption	Shareholder Fees (fees paid directly from your investment)
Operating Expenses Caption [Text]	rr_OperatingExpensesCaption	Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover.
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 63% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example.
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example does not represent the effect of any fees or other expenses assessed in connection with your variable product, and if it did, expenses would be higher. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund will invest in a portfolio of high-yielding, high-risk bonds and other income securities, such as convertible securities and preferred stock. The Fund invests, under normal circumstances, at least 80% of its net assets at the time of investment (plus any borrowings for investment purposes) in fixed-income securities (including zero coupon securities) rated below Baa by Moody’s Investors Service, Inc. (Moody’s) or below BBB by Standard & Poor’s Rating Group (S&P), or in non-rated securities considered by the Fund’s investment adviser, Invesco Advisers, Inc. (the Adviser), to be appropriate investments for the Fund. Such securities may also include Rule 144A securities, which are subject to resale restrictions. In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement. Securities rated below Baa or BBB are commonly known as junk bonds, as determined by the Adviser. There are no minimum quality ratings for investments, and as such the Fund may invest in securities which no longer make payments of interest or principal, including defaulted securities. In selecting securities for the Fund’s portfolio, the Adviser focuses on securities that it believes have favorable prospects for high current income and the possibility of growth of capital. Before purchasing securities for the Fund, the Adviser conducts a bottom-up fundamental analysis of an issuer that involves an evaluation by a team of credit analysts of an issuer’s financial condition. The fundamental analysis is supplemented by (i) an ongoing review of the securities’ relative value compared with other similar securities, and (ii) a top-down analysis of sector and macro-economic trends. The Adviser attempts to control the Fund’s risk by (i) limiting the portfolio’s assets that are invested in any one security, and (ii) diversifying the portfolio’s holdings over a number of different industries. The Adviser will consider selling a security if (i) there appears to be deterioration in a security’s risk profile, or (ii) it determines that other securities offer better value. The Fund may invest in securities of foreign issuers, including issuers located in emerging market or developing countries, which securities may be denominated in U.S. dollars or in currencies other than U.S. dollars. The Fund will limit its investments in any non-U.S. dollar denominated securities to 30% of its assets. The Fund may invest up to 20% of its assets in public bank loans made by banks or other financial institutions. Public bank loans are privately negotiated loans for which information about the issuer has been made publicly available. Public bank loans are not registered under the Securities Act of 1933, as amended, and are not publicly traded. The remaining 20% of the Fund’s assets may be invested in securities rated Baa or BBB or higher (or, if not rated, determined by the Adviser to be of comparable quality when the Adviser believes that such securities may produce attractive yields). The Fund can invest in derivatives, including credit default swap indices and forward foreign currency contracts. The Fund can invest in credit default swap indices which are credit derivatives used to hedge credit risk or take a position on a basket of credit entities. Credit default swap indices allow an investor to gain or reduce exposure on a basket of credit entities in a more efficient manner than transacting in single name credit default swaps. Unlike a credit default swap, a credit default swap index is a standardized credit security and therefore may be more liquid. The Fund can utilize forward foreign currency contracts to mitigate the risk of foreign currency exposure. A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward foreign currency contracts are used to protect against uncertainty in the level of future currency exchange rates or to gain or modify exposure to a particular currency. The Fund can use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Convertible Securities Risk. The Fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities. Defaulted Securities Risk. Defaulted securities involve the substantial risk that principal will not be repaid. Defaulted securities and any securities received in an exchange for such securities may be subject to restrictions on resale. Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors. Developing/Emerging Markets Securities Risk. Securities issued by foreign companies and governments located in developing/emerging countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries. Fixed-Income Securities Risk. Principal risks of investing in the Fund are associated with its fixed-income securities investments that are rated below investment grade. All fixed-income securities, such as junk bonds, are subject to two types of risk: credit risk and interest rate risk. Credit risk refers to the possibility that the issuer of a security will be unable to make interest payments and/or repay the principal on its debt. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. (Zero coupon securities are typically subject to greater price fluctuations than comparable securities that pay interest.) Lower Rated Securities (Junk Bonds) Risk. Junk bonds are subject to greater risk of loss of income and principal than higher rated securities and may have a higher incidence of default than higher rated securities. The prices of junk bonds are likely to be more sensitive to adverse economic changes or individual corporate developments than higher rated securities. Rule 144A securities could have the effect of increasing the level of Fund illiquidity to the extent the Fund may be unable to find qualified institutional buyers interested in purchasing the securities. Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. Public Bank Loans Risk. Certain public bank loans are illiquid, meaning the Fund may not be able to sell them quickly at a fair price. Illiquid securities are also difficult to value. Bank loans are subject to the risk of default in the payment of interest or principal on a loan, which will result in a reduction of income to the Fund, and a potential decrease in the Fund’s net asset value. Public bank loans present a greater degree of investment risk due to the fact that the cash flow or other property of the borrower securing the bank loan may be insufficient to meet scheduled payments. Management Risk. The investment techniques and risk analysis used by the Fund’s and the underlying funds’ portfolio managers may not produce the desired results. Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment; general economic and market conditions; regional or global instability; and currency and interest rate fluctuations. Preferred Securities Risk. There are special risks associated with investing in preferred securities. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments. Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance Information
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s and Morgan Stanley Variable Investment Series High Yield Portfolio’s (the predecessor fund) performance to that of a broad-based securities market/style specific benchmark. The bar chart and performance table below do not reflect charges assessed in connection with your variable product; if they did, the performance shown would be lower. The Fund’s and the predecessor fund’s past performance is not necessarily an indication of its future performance. The returns shown prior to June 1, 2010 are those of the Class X shares of the predecessor fund, which are not offered by the Fund. The predecessor fund was advised by Morgan Stanley Investment Advisors Inc. The predecessor fund was reorganized into Series I shares of the Fund on June 1, 2010. Series I shares’ returns will be different from the predecessor fund as they have different expenses. All performance shown assumes the reinvestment of dividends and capital gains.
